The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in the IMAP service in Mercur Messaging 5.0 SP3 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a long string to the (1) LOGIN or (2) SELECT command, a different set of attack vectors and possibly a different vulnerability than CVE-2003-1177.

The bug was discovered 03/16/2006. The weakness was released 03/16/2006 by Tim Taylor (Website). The advisory is available at archives.neohapsis.com.
