KSirc IRC Client Remote PRIVMSG Denial of Service Vulnerability

KSirc is prone to a remote denial-of-service vulnerability.

The issue arises when the client handles excessive string data. By exploiting this issue, a remote attacker may cause an affected client to crash.

KSirc 1.3.12 is vulnerable to this issue; other versions may also be affected.

The vendor states this issue cannot be exploited to execute arbitrary code. Successful exploits will, however, result in denial-of-service conditions in the client.
