Mozilla Foundation reports:

Security researcher Holger Fuhrmannek and Mozilla security engineer Tyson Smith reported a number of security vulnerabilities in the Graphite 2 library affecting version 1.3.5. The issue reported by Holger Fuhrmannek is a mechanism to induce stack corruption with a malicious graphite font. This leads to a potentially exploitable crash when the font is loaded. Tyson Smith used the Address Sanitizer tool in concert with a custom software fuzzer to find a series of uninitialized memory, out-of-bounds read, and out-of-bounds write errors when working with fuzzed graphite fonts.

Security researcher James Clawson used the Address Sanitizer tool to discover an out-of-bounds write in the Graphite 2 library when loading a crafted Graphite font file. This results in a potentially exploitable crash.
