CVE-2006-0747
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.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 12.7%, higher than 96% of all known CVEs. Patch or mitigate before the next change window.
