Unexpected marking work at the start of sweeping could have led to a use-after-free. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.
The Mozilla Foundation Security Advisory describes this flaw as: Unexpected marking work at the start of sweeping could have led to a use-after-free.
Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. It was discovered that Thunderbird did not properly manage certain memory operations when processing graphics shared memory. An attacker could potentially exploit this issue to escape the sandbox.
