Mac OS X Server v10.6 through v10.6.2
Impact: A remote attacker may gain access to user data via a multi-
stage attack
Description: A path resolution issue in DesktopServices is
vulnerable to a multi-stage attack. A remote attacker must first
entice the user to mount an arbitrarily named share, which may be
done via a URL scheme. When saving a file using the default save
panel in any application, and using “Go to folder” or dragging
folders to the save panel, the data may be unexpectedly saved to the
malicious share. This issue is addressed through improved path
resolution. This issue does not affect systems prior to Mac OS X
v10.6. Credit to Sidney San Martin working with DeepTech, Inc. for

Impact: Mounting a maliciously crafted disk image may lead to
arbitrary code execution
Description: A design issue exists in the handling of internet
enabled disk images. Mounting an internet enabled disk image
containing a package file type will open it rather than revealing it
in the Finder. This file quarantine feature helps to mitigate this
issue by providing a warning dialog for unsafe file types. This issue
is addressed through improved handling of package file types on
internet enabled disk images. Credit to Brian Mastenbrook working
with TippingPoint’s Zero Day Initiative for reporting this issue.

Impact: A remote attacker may cause arbitrary systems to be added to
the firewall blacklist
Description: A reverse DNS lookup is performed on remote ssh clients
that fail to authenticate. A plist injection issue exists in the
handling of resolved DNS names. This may allow a remote attacker to
cause arbitrary systems to be added to the firewall blacklist. This
issue is addressed by properly escaping resolved DNS names. Credit:
