Apple has issued a security update for Mac OS X, which fixes some older, known vulnerabilities along with some new unspecified issues.

1) Some older vulnerabilities in Apache 2 can be exploited by malicious people to inject malicious characters into log files and cause a DoS (Denial of Service).

For more information:
SA8146
SA11092
SA11170

2) Two vulnerabilities in the IPSec implementation can be exploited by malicious people to conduct MitM attacks (Man-in-the-Middle), establish unauthorised connections, or cause a DoS.

For more information:
SA11328
SA11410

3) A vulnerability within AppleFileServer can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error within the password handling. This can be exploited to cause a buffer overflow by passing an AFP "LoginExt" packet with a string in the "PathName" field, which is longer than the value specified in the packet.

Successful exploitation allows execution of arbitrary code with "root" privileges.

4) An unspecified vulnerability exists within the CoreFoundation when handling environment variables. This may potentially be a privilege escalation vulnerability. This has not been confirmed, though.

5) An unspecified vulnerability exists within RAdmin when handling large requests. This may potentially be a system compromise issue. This has not been confirmed, though. According to the vendor, only version 10.2.8 is affected.

NOTE: The severity has been set to "Highly critical" because the unspecified issues are likely to be more severe than claimed by the vendor.

This conclusion is based on the fact that Apple merely describes vulnerability 3 as an attempt to "improve the handling of long passwords". However, according to @stake, the vulnerability can in fact be exploited to compromise a vulnerable system.
