Debian DLA-1384-1 : xdg-utils security update

high Nessus Plugin ID 110160

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was found that the open_envvar function in xdg-utils does not validate strings before launching the program specified by the BROWSER environment variable, which might allow remote attackers to conduct argument-injection attacks via a crafted URL.

For Debian 7 'Wheezy', these problems have been fixed in version 1.1.0~rc1+git20111210-6+deb7u4.

We recommend that you upgrade your xdg-utils 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.

Solution

Upgrade the affected xdg-utils package.
