#CVE-2023-29531: Out-of-bound memory access in WebGL on macOS
Reporter:DoHyun Lee
Impact:high
Description
An attacker could have caused an out of bounds memory access using WebGL APIs, leading to memory corruption and a potentially exploitable crash. This bug only affects Thunderbird for macOS. Other operating systems are unaffected.

#CVE-2023-29532: Mozilla Maintenance Service Write-lock bypass
Reporter:Holger Fuhrmannek
Impact:high
Description
A local attacker can trick the Mozilla Maintenance Service into applying an unsigned update file by pointing the service at an update file on a malicious SMB server. The update file can be replaced after the signature check, before the use, because the write-lock requested by the service does not work on a SMB server.
Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.

#CVE-2023-29479: Hang when processing certain OpenPGP messages
Reporter:Ribose RNP Team
Impact:moderate
Description
Certain malformed OpenPGP messages could trigger incorrect parsing of PKESK/SKESK packets due to a bug in the Ribose RNP library used by Thunderbird up to version 102.9.1, which would cause the Thunderbird user interface to hang. The issue was discovered using Google’s oss-fuzz.

#CVE-2023-29539: Content-Disposition filename truncation leads to Reflected File Download
Reporter:Trung Pham
Impact:moderate
Description
When handling the filename directive in the Content-Disposition header, the filename would be truncated if the filename contained a NULL character. This could have led to reflected file download attacks potentially tricking users to install malware.

#CVE-2023-29541: Files with malicious extensions could have been downloaded unsafely on Linux
Reporter:Ameen Basha M K
Impact:moderate
Description
Thunderbird did not properly handle downloads of files ending in .desktop, which can be interpreted to run attacker-controlled commands. This bug only affects Thunderbird for Linux on certain Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected Linux Distributions.

#CVE-2023-29542: Bypass of file download extension restrictions
Reporter:Shaheen Fazim and Ameen Basha M K
Impact:moderate
Description
A newline in a filename could have been used to bypass the file extension security mechanisms that replace malicious file extensions such as .lnk with .download. This could have led to accidental execution of malicious code. This bug only affects Thunderbird on Windows. Other versions of Thunderbird are unaffected.

#CVE-2023-29550: Memory safety bugs fixed in Thunderbird 102.10
Reporter:Mozilla developers and community
Impact:high
Description
Mozilla developers Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.9. 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.
