Bug 794082 (CVE-2021-29959, CVE-2021-29960, CVE-2021-29961, CVE-2021-29966) – <www-client/firefox{-bin,}-{78.11.0,89.0}: multiple vulnerabilities (CVE-2021-{29959,29960,29961,29966})

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description John Helmert III 2021-06-04 02:04:33 UTC]

CVE-2021-29959:

When a user has already allowed a website to access microphone and camera, disabling camera sharing would not fully prevent the website from re-enabling it without an additional prompt. This was only possible if the website kept recording with the microphone until re-enabling the camera.

CVE-2021-29960:

Firefox used to cache the last filename used for printing a file. When generating a filename for printing, Firefox usually suggests the web page title. The caching and suggestion techniques combined may have lead to the title of a website visited during private browsing mode being stored on disk.

CVE-2021-29961:

When styling and rendering an oversized <select> element, Firefox did not apply correct clipping which allowed an attacker to paint over the user interface.

CVE-2021-29966:

Mozilla developers Christian Holler, Tooru Fujisawa, Tyson Smith reported memory safety bugs present in Firefox 88. 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.


Please stabilize the fixed ESR.
