Debian LTS: DLA-1384-1: xdg-utils security update
Summary
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.
