Fixed in
Thunderbird 91.8
In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.
#CVE-2022-1097: Use-after-free in NSSToken objects
Impact
high
Description
NSSToken objects were referenced via direct points, and could have been accessed in an unsafe way on different threads, leading to a use-after-free and potentially exploitable crash. References
Bug 1745667
#CVE-2022-28281: Out of bounds write due to unexpected WebAuthN Extensions
Impact
high
Description
If a compromised content process sent an unexpected number of WebAuthN Extensions in a Register command to the parent process, an out of bounds write would have occurred leading to memory corruption and a potentially exploitable crash. References
Bug 1755621
#CVE-2022-1197: OpenPGP revocation information was ignored
Impact
moderate
Description
When importing a revoked key that specified key compromise as the revocation reason, Thunderbird did not update the existing copy of the key that was not yet revoked, and the existing key was kept as non-revoked. Revocation statements that used another revocation reason, or that didn't specify a revocation reason, were unaffected. References
Bug 1754985
#CVE-2022-1196: Use-after-free after VR Process destruction
Impact
moderate
Description
After a VR Process is destroyed, a reference to it may have been retained and used, leading to a use-after-free and potentially exploitable crash. References
Bug 1750679
#CVE-2022-28282: Use-after-free in DocumentL10n::TranslateDocument
Impact
moderate
Description
By using a link with rel="localization" a use-after-free could have been triggered by destroying an object during JavaScript execution and then referencing the object through a freed pointer, leading to a potential exploitable crash. References
Bug 1751609
#CVE-2022-28285: Incorrect AliasSet used in JIT Codegen
Impact
moderate
Description
When generating the assembly code for MLoadTypedArrayElementHole, an incorrect AliasSet was used. In conjunction with another vulnerability this could have been used for an out of bounds memory read. References
Bug 1756957
#CVE-2022-28286: iframe contents could be rendered outside the border
Impact
low
Description
Due to a layout change, iframe contents could have been rendered outside of its border. This could have led to user confusion or spoofing attacks. References
Bug 1735265
#CVE-2022-24713: Denial of Service via complex regular expressions
Impact
low
Description
The rust regex crate did not properly prevent crafted regular expressions from taking an arbitrary amount of time during parsing. If an attacker was able to supply input to this crate, they could have caused a denial of service in the browser. References
Bug 1758509
#CVE-2022-28289: Memory safety bugs fixed in Thunderbird 91.8
Impact
high
Description
Mozilla developers and community members Nika Layzell, Andrew McCreight, Gabriele Svelto, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 91.7. 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. References
