Sandbox escape via DiskArbitration out-of-bounds read
Published Jun 9, 2020 · Updated Aug 4, 2024
Out-of-bounds read in DiskArbitration in Apple macOS Catalina before 10.15.5 allows local users to escape an application sandbox. DiskArbitration reads beyond a buffer boundary because affected input is not checked against the buffer bounds; Apple has not disclosed the file, function, or input format. Execution of a malicious local application is required, and successful exploitation removes sandbox restrictions protecting host resources.
