Date Reported:

07 Jan 2010

Affected Packages:

transmission

Vulnerable:

Yes

Security database references:

In Mitre's CVE dictionary: CVE-2010-0012.

More information:

Dan Rosenberg discovered that Transmission, a lightwight client for the Bittorrent filesharing protocol, performs insufficient sanitising of file names specified in .torrent files. This could lead to the overwrite of local files with the privileges of the user running Transmission if the user is tricked into opening a malicious torrent file.

For the stable distribution (lenny), this problem has been fixed in version 1.22-1+lenny2.

For the unstable distribution (sid), this problem has been fixed in version 1.77-1.

We recommend that you upgrade your transmission packages.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
