Description Vincent Danen 2013-04-18 16:52:21 EDT
Three flaws were corrected in the recently-released MediaWiki 1.20.4 and 1.19.5 releases:

* An internal review discovered that specially crafted Lua function names could lead to XSS [1]

* Daniel Franke reported that during SVG parsing, MediaWiki failed to prevent XML external entity (XXE) processing. This could lead to local file disclosure, or potentially remote command execution in environments that have enabled expect:// handling. [2]

* Internal review also discovered that Special:Import, and Extension:RSS failed to prevent XML external entity (XXE) processing. [3]

CVE-2013-1951 was assigned to the first issue (the XSS), the other two do not have CVEs assigned as per a discussion on oss-sec [4].
