Description

Tavis Ormandy discovered a vulnerability in the Transmission BitTorrent client; insecure RPC handling between the Transmission daemon and the client interface(s) may result in the execution of arbitrary code if a user visits a malicious website while Transmission is running.

For Debian 7 'Wheezy', these problems have been fixed in version 2.52-3+nmu3.

We recommend that you upgrade your transmission packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
