Title: Improved mod_frontpage Buffer Overflow Vulnerability

Severity: CRITICAL

Description:

Improved mod_frontpage is a module for the Apache webserver that allows for enhanced webserver interaction with the Frontpage client.

Improved mod_frontpage is susceptible to a buffer overflow condition that may allow for remote attackers to compromise the webserver. The bug is reportedly present in the fp_exec.c component and is due to insufficient bounds checking on memory-copy operations.

The vulnerable component is reportedly installed setuid root. Consequently, an attacker who successfully exploits this vulnerability may gain complete control over the host.
