Package        : xfce4-settings
CVE ID         : CVE-2022-45062
Debian Bug     : 1023732

Robin Peraglie and Johannes Moritz discovered an argument injection bug in the
xfce4-mime-helper component of xfce4-settings, which can be exploited using the
xdg-open common tool. Since xdg-open is used by multiple standard applications
for opening links, this bug could be exploited by an attacker to run arbitrary
code on an user machine by providing a malicious PDF file with specifically
crafted links.

For the stable distribution (bullseye), this problem has been fixed in
version 4.16.0-1+deb11u1.

We recommend that you upgrade your xfce4-settings packages.

For the detailed security status of xfce4-settings please refer to
its security tracker page at:
