Discussion

SSLTelnetd Remote Syslog Format String Vulnerability

Reportedly SSLTelnetd, which is available as a FreeBSD port, is affected by a remote format string vulnerability. This issue is due to an improper implementation of the 'syslog()' formatted string function.

As a result of this issue, malicious log entries containing format specifiers will be interpreted literally when logs are written; this may result in attacker-specified memory being corrupted or disclosed, leading to arbitrary code execution.

Linux Netkit netkit-telnet-ssl is affected by this issue as well.
