Description Huzaifa S. Sidhpurwala 2016-02-11 02:26:49 UTC
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 1.2.4, 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.
