Debian DLA-3671-1 : mediawiki - LTS security update

high Nessus Plugin ID 186380


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


The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3671 advisory.

- Mediawiki v1.40.0 does not validate namespaces used in XML files. Therefore, if the instance administrator allows XML file uploads, a remote attacker with a low-privileged user account can use this exploit to become an administrator by sending a malicious link to the instance administrator. (CVE-2023-3550)

- An issue was discovered in DifferenceEngine.php in MediaWiki before 1.35.12, 1.36.x through 1.39.x before 1.39.5, and 1.40.x before 1.40.1. diff-multi-sameuser (aka X intermediate revisions by the same user not shown) ignores username suppression. This is an information leak. (CVE-2023-45362)

- An issue was discovered in ApiPageSet.php in MediaWiki before 1.35.12, 1.36.x through 1.39.x before 1.39.5, and 1.40.x before 1.40.1. It allows attackers to cause a denial of service (unbounded loop and RequestTimeoutException) when querying pages redirected to other variants with redirects and converttitles set. (CVE-2023-45363)

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


Upgrade the mediawiki packages.

For Debian 10 buster, these problems have been fixed in version 1
