#FIREFOX ESR 91 UPGRADE#

Solution Upgrade to Mozilla Firefox version 91.0 or later. (CVE-2021-29990) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number. 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. (CVE-2021-29989) - Mozilla developers and community members Kershaw Chang, Philipp, Chris Peterson, and Sebastian Hengst reported memory safety bugs present in Firefox 90. Firefox Extended Support Release (ESR) is a web browser developed by the Mozilla Foundation, designed for large. (CVE-2021-29982) - Mozilla developers Christoph Kerschbaumer, Olli Pettay, Sandor Molnar, and Simon Giesecke reported memory safety bugs present in Firefox 90 and Firefox ESR 78.12. (CVE-2021-29985) - Due to incorrect JIT optimization, we incorrectly interpreted data from the wrong type of object, resulting in the potential leak of a single bit of memory. (CVE-2021-29987) - A use-after-free vulnerability in media channels could have led to memory corruption and a potentially exploitable crash. (CVE-2021-29980) - After requesting multiple permissions, and closing the first permission panel, subsequent permission panels will be displayed in a different position but still record a click in the default location, making it possible to trick a user into accepting a permission they did not want to.This bug only affects Firefox on Linux. (CVE-2021-29984) - Uninitialized memory in a canvas object could have caused an incorrect free() leading to memory corruption and a potentially exploitable crash. This led to memory corruption and a potentially exploitable crash. (CVE-2021-29983) - Instruction reordering resulted in a sequence of instructions that would cause an object to be incorrectly considered during garbage collection. Note: This issue only affected Firefox for Android.

#FIREFOX ESR 91 FOR ANDROID#

(CVE-2021-29988) - Firefox for Android could get stuck in fullscreen mode and not exit it even after normal interactions that should cause it to exit. (CVE-2021-29981) - Firefox incorrectly treated an inline list-item element as a block element, resulting in an out of bounds read or memory corruption, and a potentially exploitable crash.

#FIREFOX ESR 91 CODE#

(CVE-2021-29986) - An issue present in lowering/register allocation could have led to obscure but deterministic register confusion failures in JITted code that would lead to a potentially exploitable crash. Note: This issue only affected Linux operating systems. A suspected race condition when calling getaddrinfo led to memory corruption and a potentially exploitable crash. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2021-33 advisory. Description The version of Firefox installed on the remote Windows host is prior to 91.0.
