Date:	01/29/2007
Bugs:	#159658
ID:	200701-26

Synopsis

KSirc is vulnerable to a Denial of Service attack.

Background

KSirc is the default KDE IRC client.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
kde-base/ksirc	< 3.5.5-r1	>= 3.5.5-r1	All supported architectures

Description

KSirc fails to check the size of an incoming PRIVMSG string sent from an IRC server during the connection process.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All KSirc users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=kde-base/ksirc-3.5.5-r1"
