DescriptionNVD
In mutt before 2.3.2, the imap_auth_gss security level is mishandled.
AnalysisAI
Mutt before 2.3.2 mishandles the IMAP GSS security level due to improper integer casting and insufficient bounds checking, allowing remote attackers to trigger memory corruption and information disclosure via a crafted IMAP server response during GSS-API authentication. The vulnerability requires high attack complexity (malicious IMAP server) but affects all versions prior to 2.3.2.
