Debian DSA-3165-1 : xdg-utils - security update

high Nessus Plugin ID 81445

Language:

Synopsis

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

Description

Jiri Horner discovered a way to cause xdg-open, a tool that automatically opens URLs in a user's preferred application, to execute arbitrary commands remotely.

This problem only affects /bin/sh implementations that don't sanitize local variables. Dash, which is the default /bin/sh in Debian is affected. Bash as /bin/sh is known to be unaffected.

Solution

Upgrade the xdg-utils packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.1.0~rc1+git20111210-6+deb7u3.

For the upcoming stable (jessie) and unstable (sid) distributions, this problem will be fixed soon.
