Debian 11: DSA-5246-1 Critical MediaWiki Security Issues Fixed

Multiple security issues were discovered in MediaWiki, a website engine
for collaborative work, which could result in restriction bypass,
information leaks, cross-site scripting or denial of service.

For the stable distribution (bullseye), these problems have been fixed in
version 1:1.35.8-1~deb11u1.

We recommend that you upgrade your mediawiki packages.

For the detailed security status of mediawiki please refer to
