Multiple buffer overflows in Cyrus IMAPd before 2.2.11 may allow attackers to execute arbitrary code via (1) an off-by-one error in the imapd annotate extension, (2) an off-by-one error in "cached header handling," (3) a stack-based buffer overflow in fetchnews, or (4) a stack-based buffer overflow in imapd.

Security readout for executives and security teams

CVE-2005-0546 is a set of buffer overflow flaws in Cyrus IMAPd before 2.2.11. A successful attack could let an attacker run code on a mail server. This is most relevant to organizations still operating very old Cyrus IMAP deployments or inherited Linux distribution packages. Exposure is likely limited to legacy systems running Cyrus IMAPd before 2.2.11. Internet-facing IMAP services are the primary concern, with additional attention to systems using fetchnews. Modern supported distributions are unlikely to remain affected unless they carry obsolete packages or unmanaged source builds. Prioritize remediation if any legacy Cyrus IMAPd server is internet-facing or business-critical. The issue is old, but arbitrary code execution in mail infrastructure carries high operational risk when obsolete systems remain exposed. Mitigation focus: Upgrade Cyrus IMAPd to 2.2.11 or a vendor-fixed package.; Use the relevant Linux vendor advisory for package-specific fixed versions.; Reduce external access to affected IMAP services until upgraded..
