Arch Linux Security Advisory ASA-201911-4 ========================================= Severity: High Date : 2019-11-03 CVE-ID : CVE-2019-9636 Package : python2 Type : information disclosure Remote : Yes Link : https://security.archlinux.org/AVG-978 Summary ======= The package python2 before version 2.7.17-1 is vulnerable to information disclosure. Resolution ========== Upgrade to 2.7.17-1. # pacman -Syu "python2>=2.7.17-1" The problem has been fixed upstream in version 2.7.17. Workaround ========== None. Description =========== Python 2.7.x through 2.7.16 and 3.x through 3.7.2 is affected by improper Handling of Unicode Encoding (with an incorrect netloc) during NFKC normalization. A specially crafted URL could be incorrectly parsed by urllib.parse.urlsplit and urllib.parse.urlparse to locate cookies or authentication data and send that information to a different host than when parsed correctly. Impact ====== A remote attacker is able to craft a malicious URL and transfer private data to a different host than expected. References ========== https://python-security.readthedocs.io/vuln/urlsplit-nfkc-normalization.html https://github.com/python/cpython/commit/daad2c482c91de32d8305abbccc76a5de8… https://github.com/python/cpython/commit/f61599b050c621386a3fc6bc480359e2d3… https://security.archlinux.org/CVE-2019-9636

Arch Linux Security Advisory ASA-201910-16 ========================================== Severity: Critical Date : 2019-10-26 CVE-ID : CVE-2018-6156 CVE-2019-11757 CVE-2019-11759 CVE-2019-11760 CVE-2019-11761 CVE-2019-11762 CVE-2019-11763 CVE-2019-11764 CVE-2019-11765 CVE-2019-15903 CVE-2019-17000 CVE-2019-17001 CVE-2019-17002 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1055 Summary ======= The package firefox before version 70.0-1 is vulnerable to multiple issues including arbitrary code execution, access restriction bypass, denial of service, insufficient validation and same-origin policy bypass. Resolution ========== Upgrade to 70.0-1. # pacman -Syu "firefox>=70.0-1" The problems have been fixed upstream in version 70.0. Workaround ========== None. Description =========== - CVE-2018-6156 (arbitrary code execution) A heap-based buffer overflow has been found in Firefox before 70.0, where an incorrect derivation of a packet length in WebRTC caused heap corruption via a crafted video file. - CVE-2019-11757 (arbitrary code execution) A use-after-free issue has been found in the IndexedDB component of Firefox before 70.0 and Thunderbird before 68.2. When storing a value in IndexedDB, the value's prototype chain is followed and it was possible to retain a reference to a locale, delete it, and subsequently reference it. - CVE-2019-11759 (arbitrary code execution) A stack-based buffer overflow has been found in the HKDF output of Firefox before 70.0 and Thunderbird before 68.2. An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the stack. - CVE-2019-11760 (arbitrary code execution) A fixed-size stack buffer overflow has been found in nrappkit, in the WebRTC signaling code of Firefox before 70.0 and Thunderbird before 68.2. - CVE-2019-11761 (access restriction bypass) An issue has been found in Firefox before 70.0 and Thunderbird before 68.2, where by using a form with a data URI it was possible to gain access to the privileged JSONView object that had been cloned into content. Impact from exposing this object appears to be minimal, however it was a bypass of existing defense in depth mechanisms. - CVE-2019-11762 (same-origin policy bypass) A same-origin policy bypass has been found in Firefox before 70.0 and Thunderbird before 68.2 where, if two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross- origin window. - CVE-2019-11763 (insufficient validation) An issue has been found in Firefox before 70.0 and Thunderbird before 68.2, where failure to correctly handle null bytes when processing HTML entities resulted in incorrectly parsing these entities. This could have led to HTML comment text being treated as HTML which could have led to XSS in a web application under certain conditions. It could have also led to HTML entities being masked from filters, enabling the use of entities to mask the actual characters of interest from filters. - CVE-2019-11764 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 70.0 and Thunderbird before 68.2. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could be exploited to run arbitrary code. - CVE-2019-11765 (insufficient validation) Incorrect permissions could be granted to a website in Firefox before 70.0. A compromised content process could send a message to the parent process that would cause the 'Click to Play' permission prompt to be shown. However, due to lack of validation from the parent process, if the user accepted the permission request an attacker-controlled permission would be granted rather than the 'Click to Play' permission. - CVE-2019-15903 (denial of service) A security issue has been found in libexpat before 2.2.8, where crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read - CVE-2019-17000 (access restriction bypass) A CSP bypass has been found in Firefox 69, where an object tag with a data URI did not correctly inherit the document's Content Security Policy. This allowed a CSP bypass in a cross-origin frame if the document's policy explicitly allowed data: URIs. - CVE-2019-17001 (access restriction bypass) A CSP bypass has been found in Firefox 69, where a Content-Security- Policy that blocks in-line scripts could be bypassed using an object tag to execute JavaScript in the protected document (cross-site scripting). This is a separate bypass from CVE-2019-17000. - CVE-2019-17002 (access restriction bypass) An issue has been found in Firefox before 70.0 where, if upgrade- insecure-requests was specified in the Content Security Policy, and a link was dragged and dropped from that page, the link was not upgraded to https. Impact ====== A remote attacker can crash Firefox, bypass security measures or execute arbitrary code.

It could have also led to HTML entities being masked from filters, enabling the use of entities to mask the actual characters of interest from filters. - CVE-2019-11764 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 70.0 and Thunderbird before 68.2. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort some of these could be exploited to run arbitrary code. - CVE-2019-15903 (denial of service) A security issue has been found in libexpat before 2.2.8, where crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read Impact ====== A remote attacker could crash Thunderbird, bypass security measures or execute arbitrary code.

[ASA-201910-14] php: arbitrary code execution
by Remi Gacogne 28 Oct '19

28 Oct '19

Arch Linux Security Advisory ASA-201910-14 ========================================== Severity: Critical Date : 2019-10-25 CVE-ID : CVE-2019-11043 Package : php Type : arbitrary code execution Remote : Yes Link : https://security.archlinux.org/AVG-1052 Summary ======= The package php before version 7.3.11-1 is vulnerable to arbitrary code execution. Resolution ========== Upgrade to 7.3.11-1. # pacman -Syu "php>=7.3.11-1" The problem has been fixed upstream in version 7.3.11. Workaround ========== If nginx and php-fpm share the same filesystem, one can first check the script actually exists, so the malicious request will never make it to php-fpm (it is usually done using something like `try_files $uri =404`). Or there may be cgi.fix_pathinfo=0 which will also prevent exploitation. Description =========== A buffer underflow issue has been found in the php-fpm component of php before 7.3.11, 7.2.24 and 7.1.33, leading to remote code execution in certain nginx + php-fpm configurations. This vulnerability can be exploited if the fastcgi_split_path_info directive contains a regexp that can be broken by an attacker by supplying %0a in the path info which results in the fastcgi_param PATH_INFO being empty. Impact ====== A remote attacker is able to execute arbitrary code on the affected host by supplying %0a in the path info if php-fpm is used with a vulnerable nginx configuration.

Arch Linux Security Advisory ASA-201910-13 ========================================== Severity: High Date : 2019-10-23 CVE-ID : CVE-2019-18182 CVE-2019-18183 Package : pacman Type : arbitrary command execution Remote : Yes Link : https://security.archlinux.org/AVG-1049 Summary ======= The package pacman before version 5.2.0-1 is vulnerable to arbitrary command execution. Resolution ========== Upgrade to 5.2.0-1. # pacman -Syu "pacman>=5.2.0-1" The problems have been fixed upstream in version 5.2.0. Workaround ========== For CVE-2019-18182: Ensure `XferCommand` is commented out in `/etc/pacman.conf` For CVE-2019-18183: Ensure `UseDelta` is commented out in `/etc/pacman.conf` Description =========== - CVE-2019-18182 (arbitrary command execution) pacman before 5.2 is vulnerable to arbitrary command injection in src/pacman/conf.c in the download_with_xfercommand() function. This can be exploited when unsigned databases are used. To exploit the vulnerability, the user must enable a non-default XferCommand and retrieve an attacker-controlled crafted database and package. - CVE-2019-18183 (arbitrary command execution) pacman before 5.2 is vulnerable to arbitrary command injection in lib/libalpm/sync.c in the apply_deltas() function. This can be exploited when unsigned databases are used. To exploit the vulnerability, the user must enable the non-default delta feature and retrieve an attacker-controlled crafted database and delta file. Impact ====== A remote attacker is able to execute arbitrary commands on the host with a specially crafted database and a package or delta file.
