CVE-2018-15920
Adobe Acrobat and Reader versions 2018.011.20063 and earlier, 2017.011.30102 and earlier, and 2015.006.30452 and earlier have an use after free vulnerability.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.83%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
