LOW 3.7
DescriptionNVD
mutt before 2.3.2 sometimes uses strfcpy instead of memcpy for the IMAP auth_cram MD5 digest.
AnalysisAI
Mutt before 2.3.2 uses an unsafe string copy function (strfcpy) instead of memcpy when handling MD5 digest data in IMAP CRAM authentication, allowing attackers to potentially forge IMAP credentials by triggering buffer manipulation during the authentication handshake. The vulnerability requires manual connection attempt to a malicious IMAP server and affects network IMAP authentication flows, though the low CVSS score (3.7) reflects high attack complexity and integrity impact only.
