Gentoo Linux Security Advisory

Title: CTorrent: User-assisted arbitrary code execution (GLSA 201311-11)
Severity: normal
Exploitable: remote
Date: November 20, 2013
Updated: November 22, 2013
Bug(s): #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: net-p2p/ctorrent
Vulnerable: < 3.3.2-r1
Unaffected: >= 3.3.2-r1
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-p2p/ctorrent-3.3.2-r1"

CVE-2009-1759
