Synopsis
=======
KSirc is vulnerable to a Denial of Service attack.

Background
=========
KSirc is the default KDE IRC client.

Affected packages
================
    -------------------------------------------------------------------
     Package         /  Vulnerable  /                       Unaffected
    -------------------------------------------------------------------
  1  kde-base/ksirc     < 3.5.5-r1                         >= 3.5.5-r1

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"
