CVE-2023-29532

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. This
vulnerability affects Firefox < 112, Firefox ESR < 102.10, and Thunderbird
< 102.10.
