NVD Description

Note: Versions mentioned in the description apply only to the upstream libreoffice-langpack-cy package and not the libreoffice-langpack-cy package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The SwCTBWrapper::Read function in sw/source/filter/ww8/ww8toolbar.cxx in LibreOffice before 5.4.6.1 and 6.x before 6.0.2.1 does not validate a customizations index, which allows remote attackers to cause a denial of service (heap-based buffer overflow with write access) or possibly have unspecified other impact via a crafted document that contains a certain Microsoft Word record.
