that will be flagged as potentially unsafe under certain
circumstances, such as when they are downloaded from a web page.
While these content types are not automatically launched, if manually
opened they could lead to the execution of a malicious payload. This
update improves the system's ability to notify users before handling
content types used by Automator, Help, Safari, and Terminal. On Mac
OS X v10.4 this functionality is provided by the Download Validation
feature. On Mac OS X v10.5 this functionality is provided by the

preferences. This issue does not affect systems running Mac OS X
v10.5.
Mail
CVE-ID: CVE-2008-1576
Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11
Impact: Sending mail through an SMTP server over IPv6 may lead to an
unexpected application termination, information disclosure, or
arbitrary code execution
Description: An uninitialized buffer issue exists in Mail. When
sending mail through an SMTP server over IPv6, Mail may use a buffer
containing partially uninitialized memory, which could result in the
disclosure of sensitive information to message recipients and mail
server administrators. This could also potentially lead to an
unexpected application termination or arbitrary code execution. This
update addresses the issue by properly initializing the variable.
This issue does not affect systems running Mac OS X v10.5 or later.

Impact: Passwords supplied to sso_util are exposed to other local
users
Description: The sso_util command-line tool required that passwords
be passed to it in its arguments, potentially exposing the passwords
to other local users. Passwords exposed include those for users,
administrators, and the KDC administration password. This update
makes the password parameter optional, and sso_util will prompt for
the password if needed. Credit to Geoff Franks of Hauptman Woodward
Institute for reporting this issue.
