NVD Description

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

LibreOffice can read CFF fonts, which may be embedded in documents. A stack buffer overflow existed when reading the hints of a glyph. The number of hints was checked against the wrong bound, so a glyph declaring more hints than the array can hold wrote past its end. In fixed versions the hint count is checked against the capacity the array really has.
