APPLE-SA-2009-08-05-1 Security Update 2009-003 / Mac OS X v10.5.8

Security Update 2009-003 / Mac OS X v10.5.8 is now available and
addresses the following:

bzip2
CVE-ID:  CVE-2008-1372
Available for:  Mac OS X v10.4.11, Mac OS X Server v10.4.11,
Mac OS X v10.5 through v10.5.7, Mac OS X Server v10.5 through v10.5.7
Impact:  Decompressing maliciously crafted data may lead to an
unexpected application termination
Description:  An out-of-bounds memory access exists in bzip2. Opening
a maliciously crafted compressed file may lead to an unexpected
application termination. This update addresses the issue by updating
bzip2 to version 1.0.5. Further information is available via the
bzip2 web site at http://bzip.org/

CFNetwork
CVE-ID:  CVE-2009-1723
Available for:  Mac OS X v10.5 through v10.5.7,
Mac OS X Server v10.5 through v10.5.7
Impact:  A maliciously crafted website may control the displayed
website URL in a certificate warning
Description:  When Safari reaches a website via a 302 redirection and
a certificate warning is displayed, the warning will contain the
original website URL instead of the current website URL. This may
allow a maliciously crafted website that is reached via an open
redirector on a user-trusted website to control the displayed website
URL in a certificate warning. This issue was addressed by returning
the correct URL in the underlying CFNetwork layer. This issue does
not affect systems prior to Mac OS X v10.5. Credit to Kevin Day of
Your.Org, and Jason Mueller of Indiana University for reporting this
issue.

ColorSync
CVE-ID:  CVE-2009-1726
Available for:  Mac OS X v10.4.11, Mac OS X Server v10.4.11,
Mac OS X v10.5 through v10.5.7, Mac OS X Server v10.5 through v10.5.7
Impact:  Viewing a maliciously crafted image with an embedded
ColorSync profile may lead to an unexpected application termination
or arbitrary code execution
Description:  A heap buffer overflow exists in the handling of images
with an embedded ColorSync profile. Opening a maliciously crafted
image with an embedded ColorSync profile may lead to an unexpected
application termination or arbitrary code execution. This update
addresses the issue by performing additional validation of ColorSync
profiles. Credit to Chris Evans of the Google Security Team for
reporting this issue.

CoreTypes
CVE-ID:  CVE-2009-1727
Available for:  Mac OS X v10.5 through v10.5.7,
Mac OS X Server v10.5 through v10.5.7
Impact:  Users are not warned before opening certain potentially
unsafe content types
Description:  This update extends the system's list of content types
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 JavaScript
payload. This update improves the system's ability to notify users
before handling content types used by Safari. Credit to Brian
Mastenbrook, and Clint Ruoho of Laconic Security for reporting this
issue.

Dock
CVE-ID:  CVE-2009-0151

four-finger Multi-Touch gestures
Description:  The screen saver does not block four-finger Multi-Touch
gestures, which may allow a person with physical access to a locked
system to manage applications or use Expose. This update addresses
the issue by properly blocking Multi-Touch gestures when the screen
saver is running. This issue only affects systems with a Multi-Touch
trackpad.
