TITLE:
Apple Mac OS X Security Update Fixes Multiple Vulnerabilities

SECUNIA ADVISORY ID:
SA31326

VERIFY ADVISORY:
http://secunia.com/advisories/31326/

CRITICAL:
Highly critical

IMPACT:
Security Bypass, Spoofing, 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 multiple
vulnerabilities.

1) A vulnerability in BIND can be exploited to poison the DNS cache.

For more information:
SA30973

2) A boundary error exists in CarbonCore when handling filenames.
This can be exploited to cause a stack-based buffer overflow via
overly long filenames.

Successful exploitation of the vulnerability may allow execution of
arbitrary code.

3) Multiple errors exist in CoreGraphics when processing received
arguments. These can be exploited to trigger a memory corruption by
e.g. tricking a user into visiting a specially crafted website.

Successful exploitation of the vulnerability may allow execution of
arbitrary code.

4) An integer overflow error exists in CoreGraphics when handling PDF
files. This can be exploited to cause a heap-based buffer overflow via
a specially crafted PDF file.

Successful exploitation of the vulnerability may allow execution of
arbitrary code.

5) Multiple errors in QuickLook when downloading Microsoft Office
files can be exploited to cause a memory corruption.

Successful exploitation of the vulnerability may allow execution of
arbitrary code.

6) An error exists in the Data Detectors engine when viewing a
specially crafted message. This can be exploited to consume overly
large resources and trigger an application using the engine to
terminate.

7) The problem is that the "Repair Permissions" tool included in Disk
Utility sets the "setuid" bit on "/usr/bin/emacs". This can be
exploited to execute arbitrary commands with system privileges.

8) An error in OpenLDAP when parsing ASN.1 BER encoded packets can be
exploited to cause a DoS.

For more information:
SA30853

9) A boundary error exists in the OpenSSL "SSL_get_shared_ciphers()"
function.

For more information see vulnerability #4 in:
SA22130

10) Some vulnerabilities in PHP can be exploited malicious users to
bypass certain security restrictions, and potentially by malicious
people to cause a DoS (Denial of Service) or to compromise a
vulnerable system.

For more information:
SA30048

11) Two vulnerabilities in rsync can be exploited by malicious users
to bypass certain security restrictions.

For more information:
SA27863
