KSirc is vulnerable to a Denial of Service attack.
KSirc is the default KDE IRC client.
KSirc fails to check the size of an incoming PRIVMSG string sent from an IRC server during the connection process.
A malicious IRC server could send a long PRIVMSG string to the KSirc client causing an assertion failure and the dereferencing of a null pointer, resulting in a crash.
There is no known workaround at this time.
All KSirc users should upgrade to the latest version:
