Description Vincent Danen 2012-03-05 12:02:42 EST
It was reported [1],[2] that mwlib suffered from a flaw that could allow a remote attacker to perform a denial of service attack on a mwlib installation by forcing it to parse a specially-crafted #iferror magic function.  This has been corrected [3] in upstream version 0.13.5.
