CVE-2022-22606

Code execution via otool out-of-bounds read

Published Mar 18, 2022 · Updated Aug 3, 2024

An out-of-bounds read in Apple Xcode before 13.3 allows context-dependent attackers to crash otool or execute code through a malicious file. The otool binary reads beyond a buffer boundary while parsing the crafted file because its bounds checks do not reject the malformed input. Exploitation requires a user to open the file; successful processing can terminate the application or run attacker-controlled code in the user's context.
