CVE-2019-8731

A permissions issue existed in which execute permission was incorrectly granted.

MEDIUM 5.5EPSS 0.76%

Does this matter?

Lower severity and a low EPSS score (0.76%). Track it; it rarely justifies an emergency change on its own.

Description

A permissions issue existed in which execute permission was incorrectly granted. This issue was addressed with improved permission validation. This issue is fixed in iOS 13. Processing a maliciously crafted file may disclose user information.
