Thunderbird Security Flaws: Don’t Worry, Your Emails are Safe!
Thunderbird email remains secure due to disabled scripting, but watch out for memory safety bugs in Firefox and Thunderbird. Exploits could lead to memory corruption, and in worst cases, allow arbitrary code execution.
Hot Take:
Looks like Thunderbird’s memory safety bugs are trying to fly south for the winter, but instead, they’re just crashing into our browsers!
Key Points:
- Large allocation checks in Angle for GLSL shaders are too lenient on macOS.
- Potential out-of-bounds access when allocating more than 8192 ints in private shader memory.
- Out-of-memory scenarios leading to memory corruption issues.
- Memory safety bugs reported in Firefox 127, Firefox ESR 115.12, and Thunderbird 115.12.
- Potential for these bugs to be exploited to run arbitrary code.
