Firefox 121 and Firefox ESR 115.6 Audit
Security Software VulnerabilityAudit All Outdated Firefox Installations in Your Network
On the 19th of December, 2023 Mozilla released its new versions of Firefox 121, and Firefox ESR 115.6. These releases contain multiple changes with additional functionality and security fixes. New features, fixes, and changes in Firefox 121, as listed on Mozilla’s release page are as follows:
- Firefox now prompts Windows users to install the Microsoft AV1 Video Extension to enable hardware decoding support for the AV1 video codec from
about:supportif not already installed. - Firefox 121 supports Voice Control commands on macOS systems.
- On Linux, Firefox now defaults to the Wayland compositor when available instead of XWayland. This brings support for touchpad & touchscreen gestures, swipe-to-nav, per-monitor DPI settings, better graphics performance, and more.
- Firefox 121 can force links to always be underlined. This option can be enabled in the Browsing section of the Firefox Settings menu.
- The PDF viewer now includes a floating button to simplify deleting drawings, text, and images added in PDFs.
As always, the new releases also come with several security fixes, 18 in Firefox 121 and 11 in Firefox ESR 115.6. 5 of these issues received a high severity rating:
- CVE-2023-6856: Heap-buffer-overflow affecting WebGL DrawElementsInstanced method with Mesa VM driver
- CVE-2023-6865: Potential exposure of uninitialized data in EncryptingOutputStream
- CVE-2023-6864: Memory safety bugs fixed in Firefox 121, Firefox ESR 115.6, and Thunderbird 115.6
- CVE-2023-6873: Memory safety bugs fixed in Firefox 121
- CVE-2023-6135: NSS susceptible to “Minerva” attack
