Description:Summary:
The remote host is missing an update for the 'mediawiki' package(s) announced via the MGASA-2015-0421 advisory.

Vulnerability Insight:
Updated mediawiki packages fix security vulnerabilities:

In MediaWiki before 1.23.11, the API failed to correctly stop adding new
chunks to the upload when the reported size was exceeded, allowing a
malicious user to upload add an infinite number of chunks for a single file
upload (CVE-2015-8001).

In MediaWiki before 1.23.11, a malicious user could upload chunks of 1 byte
for very large files, potentially creating a very large number of files on
the server's filesystem (CVE-2015-8002).

In MediaWiki before 1.23.11, it is not possible to throttle file uploads,
or in other words, rate limit them (CVE-2015-8003).

In MediaWiki before 1.23.11, a missing authorization check when removing
suppression from a revision allowed users with the 'viewsuppressed' user
right but not the appropriate 'suppressrevision' user right to unsuppress
revisions (CVE-2015-8004).

In MediaWiki before 1.23.11, thumbnails of PNG files generated with
ImageMagick contained the local file path in the image (CVE-2015-8005).

Affected Software/OS:
'mediawiki' package(s) on Mageia 5.

Solution:
Please install the updated package(s).
