CVE-2018-11498
Remote attackers can leverage this vulnerability to cause a denial of service via a crafted input file, as well as achieve remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.01%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
