CVE-2023-29532  (opens in a new tab)

How to fix?

Upgrade Alpine:3.20 firefox-esr to version 102.10.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream firefox-esr package and not the firefox-esr package as distributed by Alpine. See How to fix? for Alpine:3.20 relevant fixed versions and status.

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.
