CVE-2017-5121
Inappropriate use of JIT optimisation in V8 in Google Chrome prior to 61.0.3163.100 for Linux, Windows, and Mac allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page, related to the escape analysis phase.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (5.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
