KSirc is vulnerable to a Denial of Service attack.
|Package||kde-base/ksirc on all architectures|
|Affected versions||< 3.5.5-r1|
|Unaffected versions||>= 3.5.5-r1|
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:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-base/ksirc-3.5.5-r1"
