Apple released security updates for multiple products. The exploitation of some of these security flaws will allow an attacker to crash the application or potentially control affected systems. However, a patch management solution can stop the exploitation.
The Apple Security updates for macOS include fixes for 59 vulnerabilities, which came to light using a vulnerability scanning tool, which could allow an attacker to execute arbitrary code with kernel or system privileges, gain elevated privileges, bypass privacy preferences, read restricted memory, cause unexpected application termination or heap corruption, disclose process memory, read arbitrary files, etc.
An improper input validation issue existed in the parsing of URLs of the macOS Server. The flaw could be used by an attacker to conduct open redirect or cross-site scripting attacks. This vulnerability, which affects macOS Big Sur, was addressed with improved input validation.
A Use-After-Free vulnerability has been fixed in Apple Safari. Processing of maliciously crafted web content may allow attackers to launch arbitrary code execution. The issue was fixed by improving memory management.
