Description Adam Mariš 2015-11-06 13:51:49 UTC

It was found that crafted Microsoft Word DOC file can be used to specify a document buffer that is too small for the amount of data provided for it. Failure to detect the discrepancy allows an attacker to cause denial of service (memory corruption and application crash) and possible execution of arbitrary code.

Products affected are LibreOffice < 4.4.5 and OpenOffice <= 4.1.1.
