Apple Security Updates May 2020


Apple has released a set of security updates for the second time this month. The updates include fixes for vulnerabilities in macOS, Safari, watchOS, iOS, and tvOS. There are a total of 56 CVEs. However, these CVEs can be detected using a vulnerability scanning tool.

33 vulnerabilities were fixed in macOS and 14 vulnerabilities in Safari. Eleven vulnerabilities in macOS lead to arbitrary code execution. 13 out of 14 vulnerabilities in Safari also lead to code execution. Using a patch management tool, these vulnerabilities can be remediated.

CVE-2019-8786 is considered critical as it allows arbitrary code execution with kernel privileges. CVE-2019-8786 is a memory corruption issue in the ‘Kernel‘ which was addressed with improved memory handling. However, CVE-2019-8802 is a validation issue in ‘manpages‘ which allows an attacker to gain root privileges. Moreover, CVE-2019-8813 is a vulnerability affecting ‘WebKit’ component which leads to universal cross site scripting.

The other vulnerabilities affecting macOS allow an attacker to leak and read restricted memory, exfiltrate data with improper URL processing, leak sensitive user information, perform a denial of service attacks, elevate privileges, determine kernel memory layout and check for the existence of arbitrary files.

However, we strongly recommend system administrators to keep their systems up-to-date with the latest patches in Apple Security update.
