Stack-based buffer overflow in Cyrus IMAP Server 2.2.4 through 2.2.8, with the imapmagicplus option enabled, allows remote attackers to execute arbitrary code via a long (1) PROXY or (2) LOGIN command, a different vulnerability than CVE-2004-1015.

Security readout for executives and security teams

This is an old remote code execution issue in Cyrus IMAP Server. If a business still runs Cyrus IMAP 2.2.4 through 2.2.8 with imapmagicplus enabled, a remote attacker could crash or potentially take control of the mail service using oversized IMAP commands. Exposure is likely limited to legacy Cyrus IMAP deployments, old Linux distribution packages, or embedded mail platforms still running affected 2.2.x versions with imapmagicplus enabled and IMAP reachable. Treat this as high priority only where legacy Cyrus IMAP is still present. Most modern environments will not be exposed, but affected internet-facing mail servers could represent direct infrastructure compromise risk. Mitigation focus: Identify any Cyrus IMAP 2.2.4 through 2.2.8 systems.; Check whether imapmagicplus is enabled on those systems.; Upgrade using Cyrus or distribution vendor guidance, including 2.2.9-era fixes where applicable..
