Описание

mutt before 2.3.2 sometimes truncates the hash_passwd by one byte for IMAP auth_cram MD5 digest.

A flaw was found in mutt. During the IMAP CRAM-MD5 (Challenge-Response Authentication Mechanism - Message-Digest Algorithm 5) authentication, the password hash is truncated by one byte. This issue could allow a remote attacker to potentially bypass authentication, leading to unauthorized access.
