MULTIPLE SECURITY VULNERABILITIES
This release includes important security fixes. Users are strongly encouraged
to upgrade, as the issues below may be exploitable when processing untrusted
files.
- fixed integer overflows when processing APPX compressed data streams
(by Małgorzata Olszówka)

2.12 (2026.02.02)
CRITICAL SECURITY VULNERABILITY
This release fixes a critical memory corruption vulnerability. A malicious
attacker could create a signed file, which, when verified with osslsigncode,
triggers arbitrary code execution. Any previous version of osslsigncode should
be immediately upgraded if the tool is used for verification of untrusted
files.
- fixed a buffer overflow while extracting message digests
(reported and fixed by Antoni Klajn, Opera)
