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.
Conclusion & alert: CVE-2006-0747 is rated High Exploit Risk (74.1/100): CVSS Medium severity, with high exploitation likelihood (EPSS 45.93%, 98th percentile).
