Arch Linux Security Advisory ASA-201907-4 ========================================= Severity: Critical Date : 2019-07-17 CVE-ID : CVE-2019-9811 CVE-2019-11709 CVE-2019-11710 CVE-2019-11711 CVE-2019-11712 CVE-2019-11713 CVE-2019-11714 CVE-2019-11715 CVE-2019-11716 CVE-2019-11717 CVE-2019-11718 CVE-2019-11719 CVE-2019-11720 CVE-2019-11721 CVE-2019-11723 CVE-2019-11724 CVE-2019-11725 CVE-2019-11727 CVE-2019-11728 CVE-2019-11729 CVE-2019-11730 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1002 Summary ======= The package firefox before version 68.0-1 is vulnerable to multiple issues including arbitrary code execution, access restriction bypass, cross-site request forgery, sandbox escape, arbitrary filesystem access, content spoofing, cross-site scripting, denial of service, information disclosure, insufficient validation and silent downgrade. Resolution ========== Upgrade to 68.0-1. # pacman -Syu "firefox>=68.0-1" The problems have been fixed upstream in version 68.0. Workaround ========== None. Description =========== - CVE-2019-9811 (sandbox escape) A sandbox escape has been found in Firefox before 68.0, by installing a malicious language pack and then opening a browser feature that used the compromised translation. - CVE-2019-11709 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 68.0. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2019-11710 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 68.0. Some of these bugs showed evidence of memory corruption and Mozilla presumes that with enough effort that some of these could be exploited to run arbitrary code. - CVE-2019-11711 (access restriction bypass) In Firefox before 68.0, when an inner window is reused, it does not consider the use of document.domain for cross-origin protections. If pages on different subdomains ever cooperatively use document.domain, then either page can abuse this to inject script into arbitrary pages on the other subdomain, even those that did not use document.domain to relax their origin security. - CVE-2019-11712 (cross-site request forgery) In Firefox before 68.0, POST requests made by NPAPI plugins, such as Flash, that receive a status 308 redirect response can bypass CORS requirements. This can allow an attacker to perform Cross-Site Request Forgery (CSRF) attacks. - CVE-2019-11713 (arbitrary code execution) A use-after-free vulnerability can occur in the HTTP/2 component of Firefox before 68.0, when a cached HTTP/2 stream is closed while still in use, resulting in a potentially exploitable crash. - CVE-2019-11714 (arbitrary code execution) Necko can access a child on the wrong thread during UDP connections, resulting in a potentially exploitable crash in some instances. - CVE-2019-11715 (cross-site scripting) In Firefox before 68.0, due to an error while parsing page content, it is possible for properly sanitized user input to be misinterpreted and lead to XSS hazards on web sites in certain circumstances. - CVE-2019-11716 (access restriction bypass) In Firefox before 68.0, until explicitly accessed by script, window.globalThis is not enumerable and, as a result, is not visible to code such as Object.getOwnPropertyNames(window). Sites that deploy a sandboxing that depends on enumerating and freezing access to the window object may miss this, allowing their sandboxes to be bypassed. - CVE-2019-11717 (insufficient validation) A vulnerability exists in Firebox before 68.0 where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes. - CVE-2019-11718 (insufficient validation) In Firefox before 68.0, Activity Stream can display content from sent from the Snippet Service website. This content is written to innerHTML on the Activity Stream page without sanitization, allowing for a potential access to other information available to the Activity Stream, such as browsing history, if the Snipper Service were compromised. - CVE-2019-11719 (information disclosure) In Firefox before 68.0, when importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out- of-bounds read in the Network Security Services (NSS) library. - CVE-2019-11720 (insufficient validation) In Firefox before 68.0, some unicode characters are incorrectly treated as whitespace during the parsing of web content instead of triggering parsing errors. This allows malicious code to then be processed, evading cross-site scripting (XSS) filtering. - CVE-2019-11721 (content spoofing) The unicode latin 'kra' character can be used to spoof a standard 'k' character in the addressbar in Firefox before 68.0. This allows for domain spoofing attacks as do not display as punycode text, allowing for user confusion. - CVE-2019-11723 (information disclosure) A vulnerability exists in Firefox 68.0 during the installation of add- ons where the initial fetch ignored the origin attributes of the browsing context. This could leak cookies in private browsing mode or across different "containers" for people who use the Firefox Multi- Account Containers Web Extension. - CVE-2019-11724 (access restriction bypass) Application permissions in Firefox before 68.0 give additional remote troubleshooting permission to the site input.mozilla.org, which has been retired and now redirects to another site. This additional permission is unnecessary and is a potential vector for malicious attacks. - CVE-2019-11725 (access restriction bypass) In Firefox before 68.0, when a user navigates to a site marked as unsafe by the Safebrowsing API, warning messages are displayed and navigation is interrupted but resources from the same site loaded through websockets are not blocked, leading to the loading of unsafe resources and bypassing safebrowsing protections. - CVE-2019-11727 (silent downgrade) A vulnerability exists in Firefox before 68.0 where it is possible to force Network Security Services (NSS) to sign CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. - CVE-2019-11728 (information disclosure) In firefox before 68.0, the HTTP Alternative Services header, Alt-Svc, can be used by a malicious site to scan all TCP ports of any host that the accessible to a user when web content is loaded. - CVE-2019-11729 (denial of service) Empty or malformed p256-ECDH public keys may trigger a segmentation fault in Firefox before 68.0 due values being improperly sanitized before being copied into memory and used. - CVE-2019-11730 (arbitrary filesystem access) A vulnerability exists in Firefox before 68.0 where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. Luigi Gubello demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents. Impact ====== A remote attacker an access sensitive information, bypass security measures and execute arbitrary code on the affected host.
