Restricted-memory disclosure via FontParser out-of-bounds read
Published Oct 28, 2021 · Updated Aug 4, 2024
Out-of-bounds read in Apple macOS before 11.0.1 allows local users to read restricted memory through a malicious application. The FontParser component insufficiently validates application-supplied input before reading beyond a buffer boundary. Execution of the malicious application is required, and the documented consequence is restricted-memory disclosure without integrity or availability impact.
