7-Zip and Affected Versions 7-Zip versions prior to 25.01

Description 7-Zip versions before 25.01 do not consistently handle symbolic links correctly during file extraction. This can allow an attacker to perform arbitrary file writes through a crafted archive, potentially leading to code execution. A publicly available exploit exists for this issue. The vulnerability stems from improper handling of symbolic links before accessing files, allowing an attacker to bypass security restrictions.

Recommendations Update 7-Zip to version 25.01 or later.
