| Beschreibung: | Summary:
The remote host is missing an update for the 'mediawiki' package(s) announced via the MGASA-2019-0279 advisory.
Vulnerability Insight:
Updated mediawiki packages fix security vulnerabilities:
Potential XSS in jQuery (CVE-2019-11358).
An account can be logged out without using a token (CSRF) (CVE-2019-12466).
A spammer can use Special:ChangeEmail to send out spam with no rate limiting
or ability to block them (CVE-2019-12467).
Directly POSTing to Special:ChangeEmail would allow for bypassing
reauthentication, allowing for potential account takeover (CVE-2019-12468).
Exposed suppressed username or log in Special:EditTags (CVE-2019-12469).
Exposed suppressed log in RevisionDelete page (CVE-2019-12470).
Loading user JavaScript from a non-existent account allows anyone to create
the account, and XSS the users' loading that script (CVE-2019-12471).
It is possible to bypass the limits on IP range blocks (`$wgBlockCIDRLimit`)
by using the API (CVE-2019-12472).
Passing invalid titles to the API could cause a DoS by querying the entire
`watchlist` table (CVE-2019-12473).
Privileged API responses that include whether a recent change has been
patrolled may be cached publicly (CVE-2019-12474).
The mediawiki package has been updated to version 1.27.6 (Mageia 6) and 1.31.2
(Mageia 7), fixing these issues and other bugs. See the release announcements
