SECUNIA ADVISORY ID:
SA17813

VERIFY ADVISORY:
http://secunia.com/advisories/17813/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Cross Site Scripting, Spoofing, Manipulation of
data, Exposure of sensitive information, Privilege escalation, DoS,
System access

WHERE:
>From remote

OPERATING SYSTEM:
Apple Macintosh OS X
http://secunia.com/product/96/

DESCRIPTION:
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.
