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"
