NVD Description

Note: Versions mentioned in the description apply only to the upstream autocorr-sv package and not the autocorr-sv package as distributed by Oracle. See How to fix? for Oracle:9 relevant fixed versions and status.

LibreOffice converts CFF fonts to Type 1 when it subsets a font, which happens when a document is exported to PDF, and CFF fonts may be embedded in documents. A stack buffer overflow existed in that conversion. The converted operators were written into a fixed size buffer with no check that they still fit, so a glyph emitting many operators wrote past the end of the buffer. In fixed versions the remaining capacity is tracked and the conversion stops when it is used up.
