Package        : xdg-utils
Version        : 1.1.0~rc1+git20111210-6+deb7u4
CVE ID         : CVE-2017-18266
Debian Bug     : 898317


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.
