Date:	05/01/2007
Bugs:	#170303
ID:	200705-01

Synopsis

Multiple vulnerabilities have been discovered in Ktorrent allowing for the remote execution of arbitrary code and a Denial of Service.

Background

Ktorrent is a Bittorrent client for KDE.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-p2p/ktorrent	< 2.1.3	>= 2.1.3	All supported architectures

Description

Bryan Burns of Juniper Networks discovered a vulnerability in chunkcounter.cpp when processing large or negative idx values, and a directory traversal vulnerability in torrent.cpp.

Impact

A remote attacker could entice a user to download a specially crafted torrent file, possibly resulting in the remote execution of arbitrary code with the privileges of the user running Ktorrent.

Workaround

There is no known workaround at this time.

Resolution

All Ktorrent users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-p2p/ktorrent-2.1.3"
