Discussion
Talkative IRC 'PRIVMSG' Buffer Overflow Vulnerability
Talkative IRC is prone to a stack-based buffer-overflow vulnerability because it fails to bounds-check user-supplied data before copying it into an insufficiently sized buffer.
An attacker can exploit this issue by enticing an unsuspecting user into connecting to a malicious IRC server. Successful attacks will allow arbitrary code to run within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
Talkative IRC 0.4.4.16 is vulnerable; other versions may also be affected.
