Severity:	normal
Title:	CTorrent: User-assisted arbitrary code execution
Date:	11/20/2013
Bugs:	#266953
ID:	201311-11

Synopsis

A stack-based buffer overflow in CTorrent might allow a remote attacker to execute arbitrary code or cause a Denial of Service condition.

Background

CTorrent is a BitTorrent client implemented in C++ to be lightweight and quick.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-p2p/ctorrent	< 3.3.2-r1	>= 3.3.2-r1	All supported architectures

Description

CTorrent contains a stack-based buffer overflow in the btFiles::BuildFromMI function in trunk/btfiles.cpp.

Impact

A remote attacker could entice a user to open a specially crafted torrent file using CTorrent, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All CTorrent users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-p2p/ctorrent-3.3.2-r1"
