Thunderbird 102.9.0 Security Notes
#CVE-2023-25751: Incorrect code generation during JIT compilation
Reporter: Lukas Bernhard
Sometimes, when invalidating JIT code while following an iterator, the newly generated code could be overwritten incorrectly. This could lead to a potentially exploitable crash.
Dragging a URL from a cross-origin iframe that was removed during the drag could have led to user confusion and website spoofing attacks.
#CVE-2023-28162: Invalid downcast in Worklets
While implementing AudioWorklets, some code may have casted one type to another, invalid, dynamic type. This could have led to a potentially exploitable crash.
#CVE-2023-25752: Potential out-of-bounds when accessing throttled streams
When accessing throttled streams, the count of available bytes needed to be checked in the calling function to be within bounds. This may have lead future code to be incorrect and vulnerable.
#CVE-2023-28163: Windows Save As dialog resolved environment variables
When downloading files through the Save As dialog on Windows with suggested filenames containing environment variable names, Windows would have resolved those in the context of the current user.
This bug only affects Thunderbird on Windows. Other versions of Thunderbird are unaffected.
#CVE-2023-28176: Memory safety bugs fixed in Thunderbird 102.9
Reporter:Mozilla developers and community
Mozilla developers Timothy Nikkel, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.8. 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.
