Hexamail POP3 Server Remote Buffer Overflow Vulnerability

Hexamail Server is prone to a remote buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input.

Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the affected application, likely with SYSTEM-level privileges because the server must listen on TCP ports lower than 1024.

Hexamail Server 3.0.0.001 is vulnerable to this issue; other versions may also be affected.
