Discussion

LICQ Remote Buffer Overflow Vulnerability

At least one version of LICQ is vulnerable to a remote buffer overflow. By sending many characters (12000-16000) to the port on which LICQ is listening, an attacker can cause excessive data to be copied onto the stack and overwrite critical parts of the stack frame such as the calling functions' return address. Since this data is supplied by the user it can alter the program's flow of execution.
