Comment 10 Marco Benatto 2019-12-17 16:19:14 UTC 
There's a issue with fribidi when handling TrueType fonts using CMAP14 tables. A crafted input can trigger an out of bounds read at tt_cmap14_validate() function due to the lack of validation on the number of table mappings leading to denied of service.
