DESCRIPTION:
Apple has issued a security update for Mac OS X, which fixes multiple
vulnerabilities.

1) The CUPS web interface allows users to perform certain actions via
HTTP requests without performing any validity checks to verify the
requests. This can be exploited to change CUPS settings if a
logged-in administrative user visits a malicious web site.

2) A use-after-free error in CUPS when processing "get-printer-jobs"
requests can be exploited to crash "cupsd".

NOTE: "cupsd" is automatically restarted after the crash occurs.

3) An uninitialised memory access error in the CUPS web interface
when handling form variables can be exploited to disclose potentially
sensitive "cupsd" memory.

4) The "Finder" implementation leaves the ownership of selected files
unchanged when "Apply to enclosed items..." is selected in the "Get
Info" window, resulting in unexpected permissions.

5) An error in Adobe Flash Player can be exploited to bypass domain
sandbox limitations and perform unauthorized cross-domain requests.

For more information:
SA38547

6) An error in "Folder Manager" when unmounting disk images
containing a malicious "Cleanup At Startup" directory can be
exploited to delete arbitrary directories via symlink attacks.

7) An input sanitation error exists in "Help Viewer" when handling
"help:" URLs. This can be exploited to execute arbitrary JavaScript
code in the context of the local domain and disclose sensitive
information or potentially execute arbitrary code.

8) An error in iChat when handling inline image transfers can be
exploited to upload files to arbitrary locations on an AIM user's
system via directory traversal attacks.

9) Multiple integer overflow errors in LibTIFF can be exploited to
cause heap-based buffer overflows and potentially execute arbitrary
code.

For more information:
SA40181

10) An unspecified error in ImageIO when processing MPEG2 movie files
can be exploited to corrupt memory and potentially execute arbitrary
code.

11) Multiple integer underflow errors in Kerberos can be exploited to
corrupt heap memory and potentially execute arbitrary code.

For more information:
SA38080

12) An error in Kerberos can be exploited by malicious users to
trigger a double-free and potentially execute arbitrary code.

For more information:
SA39420

13) An error in Kerberos when handling authorization data can be
exploited to terminate an affected server.

14) An error in libcurl when handling compressed web content can
potentially be exploited to cause a buffer overflow and execute
arbitrary code.

For more information:
SA38427

15) The "NetAuthSysAgent" application performs certain operations
without requiring authorization, allowing local users to potentially
gain escalated privileges.

16) A format string error when handling "afp:", "cifs:", and "smb:"
URLs can be exploited to potentially execute arbitrary code.

17) Open Directory establishes plain text connections when binding to
network account servers without SSL support. This can be exploited to
potentially execute arbitrary code via Man-in-the-Middle (MitM)
attacks.

18) An error when handling local network printers having a Unicode
character in the service name can be exploited to trigger a printing
failure in certain applications.

19) An integer overflow error in the CUPS "cgtexttops" filter can be
exploited to corrupt memory and potentially execute arbitrary code.

20) An error in the Ruby WEBrick HTTP server can be exploited to
generate error pages interpreted as having an UTF-7 character set.
This can be exploited to execute arbitrary HTML and script code in a
user's browser session in context of an affected site.

21) An error in the configuration of the included Samba distribution
can be exploited to gain access to arbitrary files via symlink
attacks.

This may be related to:
SA38454

22) Multiple errors in SquirrelMail can be exploited to conduct
cross-site scripting, cross-site request forgery, session fixation,
and phishing attacks.

For more information:
SA34627
SA35073

23) Wiki Server does not specify a character set when serving HTML
documents. This can be exploited to execute arbitrary HTML and script
code in a user's browser session by making a specially crafted post or
comment.

SOLUTION:
Apply Security Update 2010-004 or update to version 10.6.4.
