CVE-2023-29532

Name	CVE-2023-29532
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. This vulnerability affects Firefox < 112, Firefox ESR < 102.10, and Thunderbird < 102.10.
Source	CVE (at NVD; CERT, LWN, oss-sec, fulldisc, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
