Assigned:2006-05-15
Published:2006-05-15
Updated:2018-10-19
Summary: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.
