CVE-2014-9668: Canonical Ubuntu Linux

High severity, CVSS 7.5. EPSS: 1.9% chance of exploitation in the next 30 days.

The woff_open_font function in sfnt/sfobjs.c in FreeType before 2.5.4 proceeds with offset+length calculations without restricting length values, which allows remote attackers to cause a denial of service (integer overflow and heap-based buffer overflow) or possibly have unspecified other impact via a crafted Web Open Font Format (WOFF) file.
