Gentoo Linux Security Advisory
Title: KSirc: Denial of Service vulnerability (GLSA 200701-26)
Severity: normal
Exploitable: remote
Date: January 29, 2007
Updated: January 30, 2007
Bug(s): #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: kde-base/ksirc
Vulnerable: < 3.5.5-r1
Unaffected: >= 3.5.5-r1
Architectures: 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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=kde-base/ksirc-3.5.5-r1" |
