Package : mediawiki
Version : 1:1.27.7-1~deb9u4
CVE ID : CVE-2020-25813 CVE-2020-25814 CVE-2020-25827 CVE-2020-25828
Multiple security issues were discovered in MediaWiki, a website engine
for collaborative work: SpecialUserRights could leak whether a user
existed or not, multiple code paths lacked HTML sanitisation allowing
for cross-site scripting and TOTP validation applied insufficient rate
limiting against brute force attempts.
For Debian 9 stretch, these problems have been fixed in version
1:1.27.7-1~deb9u4.
We recommend that you upgrade your mediawiki packages.
