[ASA-201909-2] firefox: multiple issues
Arch Linux Security Advisory ASA-201909-2 ========================================= Severity: High Date : 2019-09-04 CVE-ID : CVE-2019-5849 CVE-2019-9812 CVE-2019-11734 CVE-2019-11735 CVE-2019-11737 CVE-2019-11738 CVE-2019-11740 CVE-2019-11741 CVE-2019-11742 CVE-2019-11743 CVE-2019-11744 CVE-2019-11746 CVE-2019-11747 CVE-2019-11748 CVE-2019-11749 CVE-2019-11750 CVE-2019-11752 Package : firefox Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-1036 Summary ======= The package firefox before version 69.0-1 is vulnerable to multiple issues including arbitrary code execution, cross-site scripting, same- origin policy bypass, sandbox escape, access restriction bypass, denial of service and information disclosure. Resolution ========== Upgrade to 69.0-1. # pacman -Syu "firefox>=69.0-1" The problems have been fixed upstream in version 69.0. Workaround ========== None. Description =========== - CVE-2019-5849 (information disclosure) An out-of-bounds read vulnerability exists in the Skia graphics library shipped in Firefox before 69.0, allowing for the possible leaking of data from memory. - CVE-2019-9812 (sandbox escape) In Firefox before 69.0, given a compromised sandboxed content process due to a separate vulnerability, it is possible to escape that sandbox by loading accounts.firefox.com in that process and forcing a log-in to a malicious Firefox Sync account. Preference settings that disable the sandbox are then synchronized to the local machine and the compromised browser would restart without the sandbox if a crash is triggered. - CVE-2019-11734 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 69.0. 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-2019-11735 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 69.0. 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-2019-11737 (access restriction bypass) In Firefox before 69.0, if a wildcard ('*') is specified for the host in Content Security Policy (CSP) directives, any port or path restriction of the directive will be ignored, leading to CSP directives not being properly applied to content. - CVE-2019-11738 (access restriction bypass) In Firefox before 69.0, if a Content Security Policy (CSP) directive is defined that uses a hash-based source that takes the empty string as input, execution of any javascript: URIs will be allowed. This could allow for malicious JavaScript content to be run, bypassing CSP permissions. - CVE-2019-11740 (arbitrary code execution) Several memory safety bugs have been found in Firefox before 69.0. 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-2019-11741 (cross-site scripting) In Firefox before 69.0, a compromised sandboxed content process can perform a Universal Cross-site Scripting (UXSS) attack on content from any site it can cause to be loaded in the same process. Because addons.mozilla.org and accounts.firefox.com have close ties to the Firefox product, malicious manipulation of these sites within the browser can potentially be used to modify a user's Firefox configuration. These two sites will now be isolated into their own process and not allowed to be loaded in a standard content process. - CVE-2019-11742 (same-origin policy bypass) A same-origin policy violation can occur in Firefox before 69.0, allowing the theft of cross-origin images through a combination of SVG filters and a <canvas> element due to an error in how same-origin policy is applied to cached image content. The resulting same-origin policy violation could allow for data theft. - CVE-2019-11743 (information disclosure) In Firefox before 69.0, navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history through timing side- channel attacks. - CVE-2019-11744 (cross-site scripting) A security issue has been found in Firefox before 69.0. Some HTML elements, such as <title> and <textarea>, can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for other elements. - CVE-2019-11746 (arbitrary code execution) A use-after-free vulnerability can occur in Firefox before 69.0 while manipulating video elements if the body is freed while still in use. This results in a potentially exploitable crash. - CVE-2019-11747 (access restriction bypass) The "Forget about this site" feature in the History pane is intended to remove all saved user data that indicates a user has visited a site. This includes removing any HTTP Strict Transport Security (HSTS) settings received from sites that use it. Due to a bug in Firefox before 69.0, sites on the pre-load list also have their HSTS setting removed. On the next visit to that site if the user specifies an http: URL rather than secure https: they will not be protected by the pre- loaded HSTS setting. After that visit the site's HSTS setting will be restored. - CVE-2019-11748 (access restriction bypass) WebRTC in Firefox before 69.0 will honor persisted permissions given to sites for access to microphone and camera resources even when in a third-party context. In light of recent high profile vulnerabilities in other software, a decision was made to no longer persist these permissions. This avoids the possibility of trusted WebRTC resources being invisibly embedded in web content and abusing permissions previously given by users. Users will now be prompted for permissions on each use. - CVE-2019-11749 (information disclosure) A vulnerability exists in the WebRTC component of Firefox before 69.0 where malicious web content can use probing techniques on the getUserMedia API using constraints to reveal device properties of cameras on the system without triggering a user prompt or notification. This allows for the potential fingerprinting of users. - CVE-2019-11750 (denial of service) A type confusion vulnerability exists in the Spidermonkey component of Firefox before 69.0, which results in a non-exploitable crash. - CVE-2019-11752 (arbitrary code execution) In Firefox before 69.0, it is possible to delete an IndexedDB key value and subsequently try to extract it during conversion. This results in a use-after-free and a potentially exploitable crash. Impact ====== A remote attacker can bypass security measures, access sensitive information or execute arbitrary code on the affected host.
