MediaWiki before 1.19.24, 1.2x before 1.23.9, and 1.24.x before 1.24.2,
when using HHVM, allows remote attackers to cause a denial of service (CPU
and memory consumption) via a large number of nested entity references in
an (1) SVG file or (2) XMP metadata in a PDF file, aka a “billion laughs
attack,” a different vulnerability than CVE-2015-2937.
