CVE-2006-0747: FreeType

Medium severity, CVSS 5.0. EPSS: 12.7% chance of exploitation in the next 30 days.

Integer underflow in Freetype before 2.2 allows remote attackers to cause a denial of service (crash) via a font file with an odd number of blue values, which causes the underflow when decrementing by 2 in a context that assumes an even number of values.
