CVE-2018-15940
Adobe Acrobat and Reader versions 2018.011.20063 and earlier, 2017.011.30102 and earlier, and 2015.006.30452 and earlier have an out-of-bounds write vulnerability.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
