Description Adam Mariš 2015-11-06 13:44:04 UTC

It was found that crafted ODF document can be used to create a buffer that is too small for the amount of data loaded into it, allowing 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.
