Citadel/UX Network Data Logging Remote Format String Vulnerability

A remote format string vulnerability reportedly affects the network data logging functionality of Citadel/UX. This issue is due to a failure of the application to properly sanitize user-supplied input prior to passing it as the format specifier to a formatted printing function.

A remote attacker may leverage this issue to write to arbitrary process memory, facilitating code execution. Any code execution would take place with superuser privileges.
