Debian DSA-2791-1 : tryton-client - missing input sanitization

high Nessus Plugin ID 70748

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

Cedric Krier discovered that the Tryton client does not sanitize the file extension supplied by the server when processing reports. As a result, a malicious server could send a report with a crafted file extension that causes the client to write any local file to which the user running the client has write access.

Solution

Upgrade the tryton-client packages.

For the oldstable distribution (squeeze), this problem has been fixed in version 1.6.1-1+deb6u1.

For the stable distribution (wheezy), this problem has been fixed in version 2.2.3-1+deb7u1.
