The remote messaging service has a buffer overflow vulnerability.
The remote host is running Citadel/UX, a messaging server for Unix.
The remote version of this software is vulnerable to a buffer overflow
when performing a select() system call while providing very high file
descriptors. A remote attacker may exploit this flaw to modify at
least one byte in memory. This could lead to a denial of service, or
possibly arbitrary code execution.
