Buffer Overflow Allows Privileges Escalation in MacOS X
18 Dec. 2003
Summary
Some parts of MacOS X that did not come from BSD, as such, they contain significant security issues, and an example of this is the /System/Library/Filesystems/cd9660.fs/cd9660.util utility. This utility is suid root and is vulnerable to a classic buffer overflow due to the lack of input validation.
