CVE-2016-1521 Webfont Exploit in Firefox Because of Graphite Library
- ck2 11y agoI don't see this mentioned anywhere but it might be possible to turn graphite support off entirely via about:config gfx.font_rendering.graphite.enabled Graphite was turned on by default after FF 28 http://scripts.sil.org/cms/scripts/page.php?site_id=projects&item_id=graphite_firefox http://scripts.sil.org/cms/scripts/page.php?site_id=projects... CVE-2016-1521 http://www.talosintel.com/reports/TALOS-2016-0058/ http://www.talosintel.com/reports/TALOS-2016-0058/ Firefox builds before February 11 are vulnerable https://www.mozilla.org/en-US/security/advisories/mfsa2016-14/ https://www.mozilla.org/en-US/security/advisories/mfsa2016-1... The directrun function in directmachine.cpp in Libgraphite in Graphite 2 1.2.4, as used in Mozilla Firefox before 43.0 and Firefox ESR 38.x before 38.6.1, does not validate a certain skip operation, which allows remote attackers 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.
