The directrun function in directmachine.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox prior to 43.0 and Firefox ESR 38.x prior to 38.6.1, does not validate a certain skip operation, which allows remote malicious users to execute arbitrary code, obtain sensitive information, or cause a denial of service (out-of-bounds read and application crash) via a crafted Graphite smart font.

Updated Cisco-owned Talos has announced a bunch of font library bugs present in apps running on Windows and Linux, affecting client and-server-side machines. The problem is in the Libgraphite library, and means that applications using the library to load .TTF font files can inherit its vulnerabilities. All that's needed for a successful exploit, Talos writes, is that the user be tricked into running a Graphite-enabled application rendering a page with a maliciously crafted font. Since Libgraphit...
