Fedora 33 : mingw-python-jinja2 (2021-2ab8ebcabc)

medium Nessus Plugin ID 147782

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 33 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2021-2ab8ebcabc advisory.

- This affects the package jinja2 from 0.0.0 and before 2.11.3. The ReDoS vulnerability is mainly due to the `_punctuation_re regex` operator and its use of multiple wildcards. The last wildcard is the most exploitable as it searches for trailing punctuation. This issue can be mitigated by Markdown to format user content instead of the urlize filter, or by implementing request timeouts and limiting process memory. (CVE-2020-28493)

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

Solution

Update the affected mingw-python-jinja2 package.
