Package : xdg-utils
CVE ID : CVE-2017-18266
Debian Bug : 898317

Gabriel Corona discovered that xdg-utils, a set of tools for desktop
environment integration, is vulnerable to argument injection attacks. If
the environment variable BROWSER in the victim host has a “%s” and the
victim opens a link crafted by an attacker with xdg-open, the malicious
party could manipulate the parameters used by the browser when opened.
This manipulation could set, for example, a proxy to which the network
traffic could be intercepted for that particular execution.

For the oldstable distribution (jessie), this problem has been fixed
in version 1.1.0~rc1+git20111210-7.4+deb8u1.

For the stable distribution (stretch), this problem has been fixed in
version 1.1.1-1+deb9u1.

We recommend that you upgrade your xdg-utils packages.

For the detailed security status of xdg-utils please refer to
its security tracker page at:
