Debian DSA-5021-1 : mediawiki - security update

high Nessus Plugin ID 156114

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 / 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5021 advisory.

Multiple security issues were discovered in MediaWiki, a website engine for collaborative work:
Vulnerabilities in the mcrundo and rollback actions may allow an attacker to leak page content from private wikis or to bypass edit restrictions. For additional information please refer to https://www.mediawiki.org/wiki/2021-12_security_release/FAQ For the oldstable distribution (buster), these problems have been fixed in version 1:1.31.16-1+deb10u2. For the stable distribution (bullseye), these problems have been fixed in version 1:1.35.4-1+deb11u2. We recommend that you upgrade your mediawiki packages. For the detailed security status of mediawiki please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/mediawiki

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the mediawiki packages.

For the stable distribution (bullseye), these problems have been fixed in version 1
