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

1) An error in the CFNetwork component may allow a malicious SSL site
to pose as a trusted SLL site to CFNetwork clients (e.g. Safari).

2) Various errors in the Flash Player can be exploited by malicious
people to bypass security restrictions and compromise a vulnerable
system.

SA20971
SA21865

3) A boundary error in the ImageIO component when processing JPEG2000
images can be exploited to cause a buffer overflow and may allow
execution of arbitrary code.

4) An error in the kernel's error handling mechanism known as Mach
exception ports can be exploited by malicious, local users to execute
arbitrary code in privileged applications.

5) An unchecked error condition in the LoginWindow component may
result in Kerberos tickets being accessible to other local users
after an unsuccessful attempt to log in.

6) Another error in the LoginWindow component during the handling of
"Fast User Switching" may result in Kerberos tickets being accessible
to other local users.

7) A logic error in the LoginWindow component may allow network
accounts without GUIDs to bypass the LoginWindow service access
controls.

8) An error makes it possible for an account to manage WebObjects
applications after the "Admin" privileges have been revoked.

9) A memory corruption error in QuickDraw Manager when processing
PICT images can potentially be exploited via a specially crafted PICT
image to execute arbitrary code.

10) An error in SASL can be exploited by malicious people to cause a
DoS (Denial of Service) against the IMAP service.

11) A memory management error in WebKit's handling of certain HTML
can be exploited by malicious people to compromise a user's system.

parent to use crypt even though they appear to use ShadowHash
passwords.
