[MFSA-2022-02] Security Vulnerabilities fixed in Firefox ESR 91.5
CVE-2021-4140: Iframe sandbox bypass with XSLT (high)
It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox.CVE-2022-22737: Race condition when playing audio files (high)
Constructing audio sinks could have lead to a race condition when playing audio files and closing windows. This could have lead to a use-after-free causing a potentially exploitable crash.CVE-2022-22738: Heap-buffer-overflow in blendGaussianBlur (high)
Applying a CSS filter effect could have accessed out of bounds memory. This could have lead to a heap-buffer-overflow causing a potentially exploitable crash.CVE-2022-22739: Missing throttling on external protocol launch dialog (low)
Malicious websites could have tricked users into accepting launching a program to handle an external URL protocol.CVE-2022-22740: Use-after-free of ChannelEventQueue::mOwner (high)
Certain network request objects were freed too early when releasing a network request handle. This could have lead to a use-after-free causing a potentially exploitable crash.CVE-2022-22741: Browser window spoof using fullscreen mode (high)
When resizing a popup while requesting fullscreen access, the popup would have become unable to leave fullscreen mode.CVE-2022-22742: Out-of-bounds memory access when inserting text in edit mode (high)
When inserting text while in edit mode, some characters might have lead to out-of-bounds memory access causing a potentially exploitable crash.CVE-2022-22743: Browser window spoof using fullscreen mode (high)
When navigating from inside an iframe while requesting fullscreen access, an attacker-controlled tab could have made the browser unable to leave fullscreen mode.CVE-2022-22744: The 'Copy as curl' feature in DevTools did not fully escape website-controlled data, potentially leading to command injection (moderate)
The constructed curl command from the "Copy as curl" feature in DevTools was not properly escaped for PowerShell. This could have lead to command injection if pasted into a Powershell prompt.
This bug only affects Firefox for Windows. Other operating systems are unaffected.CVE-2022-22745: Leaking cross-origin URLs through securitypolicyviolation event (moderate)
Securitypolicyviolation events could have leaked cross-origin information for frame-ancestors violationsCVE-2022-22746: Calling into reportValidity could have lead to fullscreen window spoof (high)
A race condition could have allowed bypassing the fullscreen notification which could have lead to a fullscreen window spoof being unnoticed.
This bug only affects Thunderbird for Windows. Other operating systems are unaffected.CVE-2022-22747: Crash when handling empty pkcs7 sequence (low)
After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data could have lead to a crash. This crash is believed to be unexploitable.CVE-2022-22748: Spoofed origin on external protocol launch dialog (moderate)
Malicious websites could have confused Thunderbird into showing the wrong origin when asking to launch a program and handling an external URL protocol.CVE-2022-22751: Memory safety bugs fixed in Firefox 96 and Firefox ESR 91.5 (high)
Mozilla developers Calixte Denizet, Kershaw Chang, Christian Holler, Jason Kratzer, Gabriele Svelto, Tyson Smith, Simon Giesecke, and Steve Fink reported memory safety bugs present in Firefox 95 and Firefox ESR 91.4. 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.
