CRITICAL 9.8EPSS 9.66%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (9.66%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

Stack-based buffer overflow in Quick Heal Internet Security 10.1.0.316 and earlier, Total Security 10.1.0.316 and earlier, and AntiVirus Pro 10.1.0.316 and earlier on OS X allows remote attackers to execute arbitrary code via a crafted LC_UNIXTHREAD.cmdsize field in a Mach-O file that is mishandled during a Security Scan (aka Custom Scan) operation.
