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

2.  Impact Information


Ktorrent is a Bittorrent client for KDE.


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.


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.

3.  Resolution Information


There is no known workaround at this time.


All Ktorrent users should upgrade to the latest version:

Code Listing 3.1: Resolution

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