CVE-2023-68612023-12-19 14:15:08HIGH (9)The `nsWindow::PickerOpen(void)` method was susceptible to a heap buffer overflow when running in headless mode. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.NETWORK
CVE-2023-68602023-12-19 14:15:08MEDIUM (7)The `VideoBridge` allowed any content process to use textures produced by remote decoders. This could be abused to escape the sandbox. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.NETWORK
CVE-2023-68592023-12-19 14:15:07HIGH (9)A use-after-free condition affected TLS socket creation when under memory pressure. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.NETWORK
CVE-2023-68582023-12-19 14:15:07HIGH (9)Firefox was susceptible to a heap buffer overflow in `nsTextFragment` due to insufficient OOM handling. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.NETWORK
CVE-2023-68572023-12-19 14:15:07MEDIUM (5)When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller than necessary. *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS). Windows is unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.NETWORK
CVE-2023-68562023-12-19 14:15:07HIGH (9)The WebGL `DrawElementsInstanced` method was susceptible to a heap buffer overflow when used on systems with the Mesa VM driver. This issue could allow an attacker to perform remote code execution and sandbox escape. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.NETWORK
CVE-2023-62122023-11-21 15:15:08HIGH (9)Memory safety bugs present in Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4. 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. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.NETWORK

Why keeping Thunderbird patched matters

Unpatched third-party applications are one of the most common ways attackers get in: 57% of breached MSP clients and 32% of ransomware cases trace back to a missing patch. Every Thunderbird release that fixes a security bug is public, so attackers see it too, and an out-of-date install becomes a documented way in. Tracking the installed version on every machine and closing the gap quickly is what turns a disclosed CVE into a non-event.
