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

1) A vulnerability in the AFP Server can be exploited by guest users to disconnect AFP volumes by sending specially crafted SessionDestroy packets.

The vulnerability does reportedly not affect versions prior to 10.3.

2) A security issue in the AFP Server can be exploited to change the permissions of a write-only AFP drop box to read-write due to an incorrect setting of the guest group id.

This problem does reportedly not affect versions prior to 10.3.

3) A vulnerability in CUPS can be exploited by malicious people to cause a DoS (Denial of Service).

SA12556

4) A vulnerability in CUPS within certain methods of authenticated remote printing can be exploited to disclose users' passwords in the log files.

5) A security issue in the NetInfo Manager utility may result in an incorrect indication of the "root" account being disabled.

This problem does reportedly not affect versions prior to 10.3.

6) A security issue in postfix with "SMTPD AUTH" enabled may result in only users with the longest usernames being able to authenticate.

This problem does reportedly not affect versions prior to 10.3.

7) A vulnerability in QuickTime can potentially be exploited to compromise a user's system. The vulnerability is caused due to a boundary error within the handling of BMP images.

8) ServerAdmin comes with a self signed default certificate used for encrypted communication. However, this certificate is the same on all systems and it is therefore possible to decrypt and read captured sessions if this certificate is used.
