Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions LibreOffice versions prior to 2017-03-11

Description The issue is caused by a heap-based buffer overflow in the SVMConverter::ImplConvertFromSVM1 function, which can lead to an out-of-bounds write. This can potentially allow a remote attacker to cause a denial of service.

Recommendations For versions prior to 2017-03-11, update to a version released after 2017-03-11 to resolve the issue. As a temporary workaround, consider restricting access to the SVMConverter::ImplConvertFromSVM1 function until a patch is available.
