Discussion
Visual IRC Join Response Buffer Overflow Vulnerability
Visual IRC (ViRC) is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data before copying it to an insufficiently sized buffer.
Attackers can exploit this issue to execute arbitrary code in the context of a user running the affected application. Successful attacks will compromise the application. Failed exploits will likely cause denial-of-service conditions.
ViRC 2.0 is vulnerable; other versions may also be affected.
