27 Apr '17

Arch Linux Security Advisory ASA-201704-8 ========================================= Severity: High Date : 2017-04-27 CVE-ID : CVE-2017-1000354 CVE-2017-1000355 CVE-2017-1000356 Package : jenkins Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-255 Summary ======= The package jenkins before version 2.57-1 is vulnerable to multiple issues including cross-site request forgery, privilege escalation and arbitrary code execution. Resolution ========== Upgrade to 2.57-1. # pacman -Syu "jenkins>=2.57-1" The problems have been fixed upstream in version 2.57. Workaround ========== None. Description =========== - CVE-2017-1000354 (privilege escalation) The login command available in the remoting-based CLI stored the encrypted user name of the successfully authenticated user in a cache file used to authenticate further commands. Users with sufficient permission to create secrets in Jenkins, and download their encrypted values (e.g. with Job/Configure permission), were able to impersonate any other Jenkins user on the same instance. This has been fixed by storing the cached authentication as a hash- based MAC with a key specific to the Jenkins instance and the CLI authentication cache. Previously cached authentications are invalidated when upgrading Jenkins to a version containing a fix for this. - CVE-2017-1000355 (arbitrary code execution) Jenkins uses the XStream library to serialize and deserialize XML. Its maintainer recently published a security vulnerability that allows anyone able to provide XML to Jenkins for processing using XStream to crash the Java process. In Jenkins this typically applies to users with permission to create or configure items (jobs), views, or agents. Jenkins now prohibits the attempted deserialization of void / Void that results in a crash. - CVE-2017-1000356 (cross-site request forgery) Multiple Cross-Site Request Forgery vulnerabilities in Jenkins allowed malicious users to perform several administrative actions by tricking a victim into opening a web page. The most notable ones: SECURITY-412: Restart Jenkins immediately, after all builds are finished, or after all plugin installations and builds are finished SECURITY-412: Schedule a downgrade of Jenkins to a previously installed version if Jenkins previously upgraded itself SECURITY-413: Install and (optionally) dynamically load any plugin present on a configured update site SECURITY-414: Remove any update site from the Jenkins configuration SECURITY-415: Change a user’s API token SECURITY-416: Submit system configuration SECURITY-417: Submit global security configuration SECURITY-418, SECURITY-420: For Jenkins user database authentication realm: create an account if signup is enabled; or create an account if the victim is an administrator, possibly deleting the existing default admin user in the process SECURITY-419: Create a new agent, possibly executing arbitrary shell commands on the master node by choosing the appropriate launch method SECURITY-420: Update the node monitor data on all agents Impact ====== A remote attacker can escalate privileges, execute arbitrary code or execute cross-site request forgery which allows the attacker to perform several administrative actions.

Resolution ========== Upgrade to 1.7.1-1. # pacman -Syu "weechat>=1.7.1-1" The problem has been fixed upstream in version 1.7.1. Workaround ========== Use the following workaround for weechat>=1.1: /trigger add irc_dcc_quotes modifier "irc_in_privmsg" "${arguments} \ =~ ^[^ ]+ :${\x01}DCC SEND ${\x22} " "/.*//" Description =========== WeeChat before 1.7.1 allows a remote crash by sending a filename via DCC to the IRC plugin. This occurs in the irc_ctcp_dcc_filename_without_quotes function during quote removal, which results in a buffer overflow. Impact ====== A remote attacker is able to crash the application via a maliciously crafted DCC-request.

The event could be used by script to affect text display to make the loaded site appear to be different from the one actually loaded within the addressbar. - CVE-2017-5453 (content spoofing) A security issue has been found in Firefox < 53, allowing to inject static HTML into the RSS reader preview page due to a failure to escape characters sent as URL parameters for a feed's TITLE element. This vulnerability allows for spoofing but no scripted content can be run. - CVE-2017-5454 (access restriction bypass) A security issue has been found in Firefox < 53, allowing to bypass file system access protections in the sandbox to use the file picker to access different files than those selected in the file picker through the use of relative paths. This allows for read only access to the local file system. - CVE-2017-5455 (access restriction bypass) A security issue has been found in Firefox < 53. The internal feed reader APIs that crossed the sandbox barrier allowed for a sandbox escape and escalation of privilege if combined with another vulnerability that resulted in remote code execution inside the sandboxed process. - CVE-2017-5456 (arbitrary filesystem access) A security issue has been found in Firefox < 53, allowing to bypass file system access protections in the sandbox using the file system request constructor through an IPC message. This allows for read and write access to the local file system. - CVE-2017-5458 (cross-site scripting) An issue has been found in Firefox < 53. When a javascript: URL is drag and dropped by a user into the addressbar, the URL will be processed and executed. This allows for users to be socially engineered to execute an XSS attack on themselves. - CVE-2017-5459 (arbitrary code execution) A buffer overflow has been found in the WebGL part of Firefox < 53. It's triggerable by web content, resulting in a potentially exploitable crash. - CVE-2017-5460 (arbitrary code execution) A use-after-free vulnerability has been found in Firefox < 53. It's located in frame selection, triggered by a combination of malicious script content and key presses by a user. This results in a potentially exploitable crash. - CVE-2017-5461 (arbitrary code execution) An out-of-bounds write during Base64 decoding operation has been found in the Network Security Services (NSS) library due to insufficient memory being allocated to the buffer. An attacker could use this flaw to create a specially crafted certificate which, when parsed by NSS, could cause it to crash or execute arbitrary code, using the permissions of the user running an application compiled against the NSS library. The issue has been fixed in releases 3.29.5 and 3.30.1. - CVE-2017-5464 (arbitrary code execution) A security issue has been found in Firefox < 53. During DOM manipulations of the accessibility tree through script, the DOM tree can become out of sync with the accessibility tree, leading to memory corruption and a potentially exploitable crash. - CVE-2017-5465 (information disclosure) An out-of-bounds read has been found in Firefox < 53, while processing SVG content in ConvolvePixel. This results in a crash and also allows for otherwise inaccessible memory being copied into SVG graphic content, which could then displayed. - CVE-2017-5466 (cross-site scripting) An origin confusion issue has been found in Firefox < 53. If a page is loaded from an original site through a hyperlink and contains a redirect to a data:text/html URL, triggering a reload will run the reloaded data:text/html page with its origin set incorrectly. This allows for a cross-site scripting (XSS) attack. - CVE-2017-5467 (denial of service) A potential memory corruption and crash has been found in Firefox < 53, when using Skia content when drawing content outside of the bounds of a clipping region. - CVE-2017-5468 (denial of service) An issue with incorrect ownership model of privateBrowsing information exposed through developer tools has been found in Firefox < 53. This can result in a non-exploitable crash when manually triggered during debugging. - CVE-2017-5469 (arbitrary code execution) Several potential buffer overflows in generated code, due to the CVE-2016-6354 issue in Flex, have been fixed in Firefox 53. Impact ====== A remote attacker can spoof content, bypass access restrictions, access arbitrary files and sensitive information, crash the application and execute arbitrary code on the affected host.

Arch Linux Security Advisory ASA-201704-3 ========================================= Severity: High Date : 2017-04-07 CVE-ID : CVE-2017-0361 CVE-2017-0362 CVE-2017-0363 CVE-2017-0364 CVE-2017-0365 CVE-2017-0366 CVE-2017-0367 CVE-2017-0368 CVE-2017-0369 CVE-2017-0370 CVE-2017-0372 Package : mediawiki Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-236 Summary ======= The package mediawiki before version 1.28.1-1 is vulnerable to multiple issues including arbitrary code execution, cross-site scripting, information disclosure, cross-site request forgery, insufficient validation, open redirect and access restriction bypass. Resolution ========== Upgrade to 1.28.1-1. # pacman -Syu "mediawiki>=1.28.1-1" The problems have been fixed upstream in version 1.28.1. Workaround ========== None. Description =========== - CVE-2017-0361 (information disclosure) MediaWiki before 1.28.1 may leak passwords in plaintext. API parameters may now be marked as "sensitive" to keep their values out of the logs. - CVE-2017-0362 (cross-site request forgery) MediaWiki before 1.18.1 did not require a CSRF token for the "Mark all pages visited" action on the watchlist. - CVE-2017-0363 (open redirect) The Special:UserLogin page in MediaWiki < 1.28.1 has an open redirect issue. - CVE-2017-0364 (open redirect) The Special:Search page in MediaWiki < 1.28.1 has an open redirect issue. - CVE-2017-0365 (cross-site scripting) SearchHighlighter::removeWiki() uses a regex to remove html from snippets. The regex - /<\/?[^>]+>/ assumes that html is well-formed. As a result when using SearchHighlighter::highlightText() as the highlighting method, this can result in an XSS when $wgAdvancedSearchHighlighting is true. - CVE-2017-0366 (cross-site scripting) MediaWiki < 1.28.1 did not properly filter the DTD declaration when a SVG file was uploaded, leading to a persistent XSS. - CVE-2017-0367 (arbitrary code execution) MediaWiki before 1.28.1 uses the default system temporary directory for the LocalisationCache directory, allowing a local attacker to execute arbitrary code as the web user by crafting a cache file whose content will be passe to unserialize(). - CVE-2017-0368 (cross-site scripting) MediaWiki < 1.28.1 did not properly mark system messages as raw HTML, hence not properly escaping it. - CVE-2017-0369 (access restriction bypass) In MediaWiki < 1.28.1, a normal sysop that doesn't have the necessary rights to override a page protection can still recreate it by restoring a former revision of that page. - CVE-2017-0370 (insufficient validation) The spam blacklist in MediaWiki before 1.28.1 could be bypassed by encoding URLs inside a file inclusion syntax's link parameter. - CVE-2017-0372 (cross-site scripting) The SyntaxHighlight extension in MediaWiki before 1.28.1 does not properly validate the 'start' parameter before passing it to Pygments. Impact ====== A remote attacker might be able to access sensitive information, trick users into visiting a malicious website, execute arbitrary JavaScript on the visitor's browser, trick users into performing unwanted actions and bypass access restrictions. A local attacker might be able to execute arbitrary code with the privileges of the webserver.

[arch-security] Subject: [ASA-201704-2] python-django: multiple issues
by Jelle van der Waa 09 Apr '17

09 Apr '17

Arch Linux Security Advisory ASA-201704-2 ========================================= Severity: Medium Date : 2017-04-06 CVE-ID : CVE-2017-7233 CVE-2017-7234 Package : python-django Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-233 Summary ======= The package python-django before version 1.11-1 is vulnerable to multiple issues including cross-site scripting and open redirect. Resolution ========== Upgrade to 1.11-1. # pacman -Syu "python-django>=1.11-1" The problems have been fixed upstream in version 1.11. Workaround ========== None. Description =========== - CVE-2017-7233 (cross-site scripting) Django relies on user input in some cases (e.g. django.contrib.auth.views.login() and i18n) to redirect the user to an “on success” URL. The security check for these redirects (namely django.utils.http.is_safe_url()) considered some numeric URLs (e.g. http:999999999) “safe” when they shouldn’t be. Also, if a developer relies on is_safe_url() to provide safe redirect targets and puts such a URL into a link, they could suffer from an XSS attack. - CVE-2017-7234 (open redirect) A maliciously crafted URL to a Django site using the serve() view could redirect to any other domain. The view no longer does any redirects as they don’t provide any known, useful functionality. Note, however, that this view has always carried a warning that it is not hardened for production use and should be used only as a development aid. Impact ====== A remote attacker is able to use a specially crafted numeric-URL to execute arbitrary javascript on the client's machine and craft a malious URL to a Django site which could redirect to any other domain.

Resolution ========== Upgrade to 1.11-1. # pacman -Syu "python2-django>=1.11-1" The problems have been fixed upstream in version 1.11. Workaround ========== None. Description =========== - CVE-2017-7233 (cross-site scripting) Django relies on user input in some cases (e.g. django.contrib.auth.views.login() and i18n) to redirect the user to an “on success” URL. The security check for these redirects (namely django.utils.http.is_safe_url()) considered some numeric URLs (e.g. http:999999999) “safe” when they shouldn’t be. Also, if a developer relies on is_safe_url() to provide safe redirect targets and puts such a URL into a link, they could suffer from an XSS attack. - CVE-2017-7234 (open redirect) A maliciously crafted URL to a Django site using the serve() view could redirect to any other domain. The view no longer does any redirects as they don’t provide any known, useful functionality. Note, however, that this view has always carried a warning that it is not hardened for production use and should be used only as a development aid. Impact ====== A remote attacker is able to use a specially crafted numeric-URL to execute arbitrary javascript on the client's machine and craft a malious URL to a Django site which could redirect to any other domain.
