Fixed in Apache OpenOffice 4.1.2
Title: Memory Corruption Vulnerability (DOC Piecetable)
Version 1.0
Announced November 4, 2015

Severity: Important
There are no known exploits of this vulnerabilty.
A proof-of-concept demonstration exists.
Vendor: The Apache Software Foundation
Versions Affected
All Apache OpenOffice versions 4.1.1 and older are affected.
OpenOffice.org versions are also affected.
Mitigation
Apache OpenOffice users are urged to download and install Apache OpenOffice version 4.1.2 or later. DOC files having the defect are detected and made ineffective in 4.1.2.
Precautions
Users who do not upgrade to Apache OpenOffice 4.1.2 should be careful of .DOC files from unknown or unreliable sources.
