critical Nessus Plugin ID 156333

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-2861 advisory.

 - The Debian python-rdflib-tools 4.2.2-1 package for RDFLib 4.2.2 has CLI tools that can load Python modules from the current working directory, allowing code injection, because python -m looks in this directory, as demonstrated by rdf2dot. This issue is specific to use of the debian/scripts directory. (CVE-2019-7653)

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 rdflib packages.

For Debian 9 stretch, this problem has been fixed in version 4.2.1-2+deb9u1.
