APPLE-SA-2006-06-27 Mac OS X v10.4.7

Mac OS X v10.4.7 is now available and addresses the following
issues:

AFP
CVE-ID:  CVE-2006-1468
Available for:  Mac OS X v10.4 - v10.4.6, Mac OS X Server v10.4 -
v10.4.6
Impact:  File and folder names may be disclosed to unauthorized
users
Description:  An issue in AFP server allows search results to
include the names of files and folders for which the user
performing the search has no access. This could result in
information disclosure if the names themselves are sensitive
information. This update addresses the issue by ensuring that
search results only include items for which the user is
authorized. This issue does not affect systems prior to Mac OS X
v10.4.

ClamAV
CVE-ID:  CVE-2006-1989
Available for:  Mac OS X Server v10.4 - v10.4.6
Impact:  When virus scanning is configured to update
automatically, a malicious database mirror may cause arbitrary
code execution
Description:  An issue in ClamAV's automatic virus database
updating may result in a stack-based buffer overflow. A
malicious or spoofed ClamAV database mirror may be able to cause
arbitrary code execution with the privileges of ClamAV. The Mail
service, virus scanning, and automatic virus database updates
are off by default. This update addresses the issue by
incorporating ClamAV 0.88.2. This issue does not affect systems
prior to Mac OS X v10.4.

ImageIO
CVE-ID:  CVE-2006-1469
Available for:  Mac OS X v10.4 - v10.4.6, Mac OS X Server v10.4 -
v10.4.6
Impact:  Viewing a maliciously-crafted TIFF image may result in
an application crash or arbitrary code execution
Description:  By carefully crafting a corrupt TIFF image, an
attacker can trigger a stack-based buffer overflow which may
result in an application crash or arbitrary code execution. This
update addresses the issue by performing additional validation
of TIFF images. This issue does not affect systems prior to Mac
OS X v10.4.

launchd
CVE-ID:  CVE-2006-1471
Available for:  Mac OS X v10.4 - v10.4.6, Mac OS X Server v10.4 -
v10.4.6
Impact:  Local users may gain elevated privileges
Description:  A format string vulnerability in the setuid program
launchd may allow an authenticated local user to execute
arbitrary code with system privileges. The issue is present in
launchd's logging facility. This update addresses the issue by
performing additional validation when logging messages. This
issue does not affect systems prior to Mac OS X v10.4. Credit to
Kevin Finisterre of DigitalMunition for reporting this issue.

OpenLDAP
CVE-ID:  CVE-2006-1470
Available for:  Mac OS X v10.4 - v10.4.6, Mac OS X Server v10.4 -
v10.4.6
Impact:  Remote attackers may cause Open Directory server to
crash
Description:  By carefully crafting an invalid LDAP request, a
remote attacker may be able to trigger an assertion in the
OpenLDAP server, resulting in a denial-of-service. This update
addresses the issue by discarding the invalid request. This
issue does not affect systems prior to Mac OS X v10.4. Credit to
the Mu Security research team for reporting this issue.
