DESCRIPTION:
Dejun Meng has reported a vulnerability in BitComet Client, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error in the handling
of the publisher's name URI in a " .torrent" file. This can be
exploited to cause a buffer overflow and allows arbitrary code
execution.

Successful exploitation requires that the user is e.g. tricked into
downloading a malicious " .torrent" file and clicking on the
publisher's name link.

The vulnerability has been reported in version 0.60. Prior versions
may also be affected.

SOLUTION:
Update to version 0.61.
