TITLE:
Transmission "name" Key Directory Traversal Vulnerability

SECUNIA ADVISORY ID:
SA38005

VERIFY ADVISORY:
http://secunia.com/advisories/38005/

DESCRIPTION:
Dan Rosenberg has reported a vulnerability in Transmission, which can
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to the application not properly
sanitising the "name" key before saving files. This can be exploited
to overwrite arbitrary files on the local system when a user is
tricked into opening a specially crafted .torrent file containing
directory traversal sequences in the name key.

The vulnerability is reported in versions prior to 1.77.

SOLUTION:
Update to version 1.77.

PROVIDED AND/OR DISCOVERED BY:
Dan Rosenberg

CHANGELOG:
2010-01-08: Added CVE reference.
