CVE-2018-4997
Adobe Acrobat and Reader versions 2018.009.20050 and earlier, 2017.011.30070 and earlier, and 2015.006.30394 and earlier have an Out-of-bounds write vulnerability.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
