CVE-2014-9666: Canonical Ubuntu Linux

Medium severity, CVSS 6.8. EPSS: 4.2% chance of exploitation in the next 30 days.

The tt_sbit_decoder_init function in sfnt/ttsbit.c in FreeType before 2.5.4 proceeds with a count-to-size association without restricting the count value, which allows remote attackers to cause a denial of service (integer overflow and out-of-bounds read) or possibly have unspecified other impact via a crafted embedded bitmap.
