Multiple integer overflows in Hancom Office 2010 SE 8.5.5 allow remote attackers to execute arbitrary code via large dimension values in a (1) JPG image to the ImportGR in the JPG image filter module (HncJpeg10.flt) or (2) PNG image to the PNG image…
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
