Description Adam Mariš 2016-02-09 10:09:27 UTC 
An exploitable heap-based buffer overflow was found in the context item handling functionality of Libgraphite. A specially crafted font can cause a buffer overflow resulting in potential code execution. An attacker can provide a malicious font to trigger this vulnerability.
