CVE-2022-22603

Code execution via otool out-of-bounds read

Published Mar 18, 2022 · Updated Aug 3, 2024

An out-of-bounds read in otool in Apple Xcode before 13.3 allows attackers to crash the application or execute code by opening a crafted file. otool reads beyond a buffer boundary while parsing the file because affected builds do not validate the relevant bounds. Exploitation requires a user to open the file, and Apple has not disclosed the affected file format or specific parser routine.
