Mozilla Firefox — свободный браузер на движке Gecko

An attacker could construct a PKCS 12 cert bundle in such a way that could allow for arbitrary memory writes via PKCS 12 Safe Bag attributes being mishandled. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which could lead to website spoofing attacks. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7.

When copying a network request from the developer tools panel as a curl command the output was not being properly sanitized and could allow arbitrary commands to be hidden within. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7.

A duplicate <code>SystemPrincipal</code> object could be created when parsing a non-system html document via <code>DOMParser::ParseFromSafeString</code>. This could have lead to bypassing web security checks. This vulnerability affects Firefox < 109.

When dragging and dropping an image cross-origin, the image's size could potentially be leaked. This behavior was shipped in 109 and caused web compatibility problems as well as this security concern, so the behavior was disabled until further review. This vulnerability affects Firefox < 110.

Module load requests that failed were not being checked as to whether or not they were cancelled causing a use-after-free in <code>ScriptLoadContext</code>. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.

A compromised web child process could disable web security opening restrictions, leading to a new child process being spawned within the <code>file://</code> context. Given a reliable exploit primitive, this new process could be exploited again leading to arbitrary file read. This vulnerability affects Firefox < 109.

Due to URL previews in the network panel of developer tools improperly storing URLs, query parameters could potentially be used to overwrite global objects in privileged code. This vulnerability affects Firefox < 110.

Mozilla developers Kershaw Chang and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 109 and Firefox ESR 102.7. 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 < 110 and Firefox ESR < 102.8.

Permission prompts for opening external schemes were only shown for <code>ContentPrincipals</code> resulting in extensions being able to open them without user interaction via <code>ExpandedPrincipals</code>. This could lead to further malicious actions such as downloading files or interacting with software already installed on the system. This vulnerability affects Firefox < 110, Thunderbird < 102.8, and Firefox ESR < 102.8.
