CVE-2013-4570: Null Pointer Dereference
First published: Mon May 12 2014(Updated: )
The zend_inline_hash_func function in php-luasandbox in the Scribuntu extension for MediaWiki before 1.19.10, 1.2x before 1.21.4, and 1.22.x before 1.22.1 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via vectors related to converting Lua data structures to PHP, as demonstrated by passing { [{}] = 1 } to a module function.
