CTorrent: User-assisted arbitrary code execution

CTorrent: User-assisted arbitrary code execution A stack-based buffer overflow in CTorrent might allow a remote attacker to execute arbitrary code or cause a Denial of Service condition. ctorrent November 20, 2013 November 22, 2013: 2 266953 remote 3.3.2-r1 3.3.2-r1

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

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

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.

There is no known workaround at this time.

All CTorrent users should upgrade to the latest version:


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