CVE Reference(s):

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 passed to the CarbonCore framework file management API.

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 containing Type 1 fonts. This can be exploited to cause a heap-based buffer overflow via a font with an overly large length in 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


Solution:
Apply Security Update 2008-005.
