CVE-2006-1255 describes a critical stack-based buffer overflow vulnerability in the IMAP service of Mercur Messaging 5.0 SP3 and earlier. This flaw allows unauthenticated remote attackers to trigger a denial of service by crashing the application, and potentially execute arbitrary code, by sending an overly long string to either the LOGIN or SELECT commands. With a CVSS score of 10.0, this vulnerability is highly severe, indicating easy exploitation over the network with complete compromise of confidentiality, integrity, and availability. While not listed on the KEV catalog, multiple public exploit modules exist for Metasploit and ExploitDB, confirming its exploitability, though there is no evidence of active exploitation or significant community discussion.
