CVE-2026-6329 not yet assigned priority: Debian including 1 source packages (wolfssl), 4 status rows across 4 suites (bookworm, bullseye, sid, trixie): open 2, resolved 2.
PKCS#12 MAC verification uses an attacker-controlled comparison length, weakening the integrity check on the MAC and allowing a mismatched MAC to be accepted. The PKCS#12 verify path compared the locally computed HMAC against the MAC parsed from the PKCS#12 structure using a length taken directly from the attacker-supplied input, without first verifying that it equals the length of the digest actually produced by the configured algorithm. A truncated or zero-length stored MAC could therefore be accepted, defeating the integrity protection of the MAC.
