Last modified

CVE-2014-9663 is a vulnerability of currently unknown severity. The tt_cmap4_validate function in sfnt/ttcmap.c in FreeType before 2.5.4 validates a certain length field before that field's value is completely calculated, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted cmap SFNT table.. EPSS estimates a 5.06% chance of exploitation in the next 30 days.
