Description Adam Mariš 2016-02-09 05:05:16 EST

Exploitable NULL pointer dereference and out-of-bound access vulnerabilities were found in the bidirectional font handling functionality of Libgraphite. A specially crafted font can cause out-of-bound access resulting into remote code execution and NULL pointer dereference resulting into crash. An attacker can provide a malicious font to trigger this vulnerability.
