What to do

AI-suggested

To mitigate this vulnerability, European organizations should prioritize applying the official Apple security updates: Security Update 2022-005 for Catalina, macOS Big Sur 11.6.8, and macOS Monterey 12.5 or later. Patch management policies should ensure timely deployment across all macOS endpoints. Additionally, organizations should implement strict email and file filtering to block or quarantine suspicious Postscript files and educate users about the risks of opening unsolicited or unexpected attachments. Endpoint protection solutions with behavioral detection capabilities can help identify and block attempts to exploit this vulnerability. Restricting local user privileges and enforcing the principle of least privilege can reduce the impact of successful exploitation. Network segmentation and monitoring for unusual application crashes or memory access patterns may aid in early detection of exploitation attempts. Finally, organizations should review and harden printing and document processing workflows to minimize exposure to malicious Postscript content.

Description

An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in Security Update 2022-005 Catalina, macOS Big Sur 11.6.8, macOS Monterey 12.5. Processing a maliciously crafted Postscript file may result in unexpected app termination or disclosure of process memory.
