Debian Security Advisory
DLA-2727-1 pyxdg -- LTS security update
- Date Reported:
- 03 Aug 2021
- Affected Packages:
- Security database references:
- In Mitre's CVE dictionary: CVE-2019-12761.
- More information:
It was discovered that there was a code injection issue in PyXDG, a library used to locate freedesktop.org configuration/cache/etc. directories.
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.
For Debian 9
Stretch, these problems have been fixed in version 0.25-4+deb9u1.
We recommend that you upgrade your pyxdg packages.
