Description Jan Lieskovsky 2013-07-26 13:57:38 UTC

A NULL pointer dereference flaw was found in the way Apache OpenOffice and LibreOffice, office productivity suites, used to previously handle certain Microsoft Office Open XML format / Microsoft Office Word Macro-Enabled (DOCM) documents. A remote attacker could provide a specially-crafted DOCM format file that, when processed in some application from the Apache OpenOffice or LibreOffice suites would lead to that applications crash.

I thought our policy was to ignore plain crashes?
