CVE-2023-32443Public exploitNetwork attack vector

Memory disclosure via ICC profile out-of-bounds read

Published Jul 27, 2023 · Updated Oct 23, 2024

Out-of-bounds read in sips in Apple macOS Big Sur before 11.7.9, Monterey before 12.6.8, and Ventura before 13.5 allows attackers to expose memory. When verifying a crafted ICC color profile, sips dereferences an invalid address and reads beyond valid memory. An application or user must process the profile; the read can terminate sips or encode unintended process data in a saved profile.
