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. 

To address these security vulnerabilities, Firefox 45 and Firefox ESR 38.7 have been
updated to Graphite 2 version 1.3.6.

Security researcher Holger Fuhrmannek reported that a malicious
Graphite "smart font" could circumvent the validation of internal instruction parameters
in the Graphite 2 library using special CNTXT_ITEM instructions. This could result in
arbitrary code execution.
 This issue affected Graphite 2 version 1.3.4, which was used in the Firefox ESR branch. To address this issue and other security vulnerabilities recently disclosed by Cisco Talos affecting this version of the library, Firefox ESR has been updated to version 1.3.5, the same one used in Firefox 44.
In general this flaw cannot be exploited through email in the
Thunderbird product, but is potentially a risk in browser or browser-like contexts.
