Description Adam Mariš 2016-02-15 14:57:30 UTC 
It was found that specially crafted font can cause an out-of-bounds read potentially resulting in an information leak or denial of service. An attacker can provide a malicious font to trigger this vulnerability. When reading an invalid font where the loca table size is set to 0 an out of bounds read will occur.
