Apple has issued an update for Mac OS X, which fixes various vulnerabilities.

1) An input validation error in the kernel syscall emulation functionality when handling input parameter lists can be exploited by malicious, local users to cause a DoS (Denial of Service).

2) An error in the kernel allows installation or creation of SUID/SGID scripts, which can be exploited by malicious, local users to gain escalated privileges.

3) An error in the kernel "semop()" system call can be exploited by malicious, local users to gain escalated privileges.
