Mozilla : Security Vulnerabilities, CVEs, (Information Leak) CVSS score >= 8

The TtfUtil:LocaLookup function in TtfUtil.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, incorrectly validates a size value, which allows remote attackers to obtain sensitive information or cause a denial of service (out-of-bounds read and application crash) via a crafted Graphite smart font.

modules/libpr0n/decoders/bmp/nsBMPDecoder.cpp in Mozilla Firefox before 2.0.0.12, Thunderbird before 2.0.0.12, and SeaMonkey before 1.1.8 does not properly perform certain calculations related to the mColors table, which allows remote attackers to read portions of memory uninitialized via a crafted 8-bit bitmap (BMP) file that triggers an out-of-bounds read within the heap, as demonstrated using a CANVAS element; or cause a denial of service (application crash) via a crafted 8-bit bitmap file that triggers an out-of-bounds read. NOTE: the initial public reports stated that this affected Firefox in Ubuntu 6.06 through 7.10.
