Apple has issued a security update for Mac OS X, which fixes 13 vulnerabilities.

1) An error in the handling of HTTP headers in the Apache 2 web server can be exploited by malicious people to conduct HTTP request smuggling attacks when Apache is used in conjunction with certain proxy servers, caching servers, or web application firewalls.

For more information:
SA14530

2) An error in the Apache web server's "mod_ssl" module may be exploited by malicious people to bypass certain security restrictions.

For more information:
SA16700

3) A boundary error exists in CoreFoundation when resolving certain URL. This can be exploited to cause a heap-based buffer overflow and may allow arbitrary code execution via a specially-crafted URL. CoreFoundation is used by Safari and other applications.

4) An error in curl when handling NTLM authentication can be exploited by malicious people to compromise a user's system.

For more information:
SA17193

5) An error exists in the ODBC Administrator utility helper tool "iodbcadmintoo". This can be exploited by malicious, local users to execute commands with escalated privileges.

6) An error in OpenSSL when handling certain compatibility options can potentially be exploited by malicious people to perform protocol rollback attacks.

For more information:
SA17151

7) An error in the passwordserver when handling the creation of an Open Directory master server may cause certain credentials to be disclosed. This can be exploited by unprivileged local users to gain elevated privileges on the server.

8) An integer overflow error exists in the PCRE library that is used by Safari's JavaScript engine. This can potentially be exploited by malicious people to compromise a user's system.

For more information:
SA16502

9) An error exists in Safari when saving a downloaded file with an overly long filename. This can be exploited to cause the download file to be saved outside of the designated download directory.

10) JavaScript dialog boxes in Safari do not indicate the web site that created them. This can be exploited by malicious web sites to spoof dialog boxes.

For more information:
SA15474

11) A boundary error exists in WebKit when handling certain specially crafted content. This can be exploited to cause a heap-based buffer overflow via content downloaded from malicious web sites in applications that use WebKit such as Safari.

12) An error in sudo can be exploited by malicious, local users to execute arbitrary commands with escalated privileges.

For more information:
SA15744

13) The syslog server does not properly sanitise messages before recording them. This can be exploited to forge log entries and mislead the system administrator by supplying messages certaining control characters, such as the newline character, to the syslog server.
