Mozilla Firefox — свободный браузер на движке Gecko

An attacker could have positioned a `datalist` element to obscure the address bar. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

Members of the <code>DEVMODEW</code> struct set by the printer device driver weren't being validated and could have resulted in invalid values which in turn would cause the browser to attempt out of bounds access to related variables.<br>*This bug only affects Firefox on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

When reading a file, an uninitialized value could have been used as read limit. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

If temporary "one-time" permissions, such as the ability to use the Camera, were granted to a document loaded using a file: URL, that permission persisted in that tab for all other documents loaded from a file: URL. This is potentially dangerous if the local files came from different sources, such as in a download directory. This vulnerability affects Firefox < 111.

In multiple cases browser prompts could have been obscured by popups controlled by content. These could have led to potential user confusion and spoofing attacks. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.

Firefox did not properly handle downloads of files ending in <code>.desktop</code>, which can be interpreted to run attacker-controlled commands. <br>*This bug only affects Firefox for Linux on certain Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected Linux Distributions.*. This vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird < 102.10.

When importing a SPKI RSA public key as ECDSA P-256, the key would be handled incorrectly causing the tab to crash. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

Multiple race conditions in the font initialization could have led to memory corruption and execution of attacker-controlled code. This vulnerability affects Firefox for Android < 112, Firefox < 112, and Focus for Android < 112.

Using a redirect embedded into <code>sourceMappingUrls</code> could allow for navigation to external protocol links in sandboxed iframes without <code>allow-top-navigation-to-custom-protocols</code>. This vulnerability affects Firefox for Android < 112, Firefox < 112, and Focus for Android < 112.

Memory safety bugs present in Firefox 110. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 111.
