high Nessus Plugin ID 152194

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2727 advisory.

- A code injection issue was discovered in PyXDG before 0.26 via crafted Python code in a Category element of a Menu XML document in a .menu file. XDG_CONFIG_DIRS must be set up to trigger xdg.Menu.parse parsing within the directory containing this file. This is due to a lack of sanitization in xdg/Menu.py before an eval call. (CVE-2019-12761)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the pyxdg packages.

For Debian 9 Stretch, these problems have been fixed in version 0.25-4+deb9u1.
