Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8,
Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: Viewing or downloading a document containing a maliciously
crafted embedded font may lead to arbitrary code execution
Description: A stack buffer overlow exists in Apple Type Services'
handling of embedded fonts. Viewing or downloading a document
containing a maliciously crafted embedded font may lead to arbitrary

checking.

CFNetwork
CVE-ID: CVE-2010-1800
Available for: Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: An attacker with a privileged network position may intercept
user credentials or other sensitive information
Description: CFNetwork permits anonymous TLS/SSL connections. This
may allow a man-in-the-middle attacker to redirect connections and
intercept user credentials or other sensitive information. This issue
does not affect the Mail application. This issue is addressed by
disabling anonymous TLS/SSL connections. This issue does not affect
systems prior to Mac OS X v10.6.3. Credit to Tomas Bjurman of Sirius

Available for: Mac OS X Server v10.5.8, Mac OS X Server v10.6.4
Impact: Multiple vulnerabilities in ClamAV
Description: Multiple vulnerabilities exist in ClamAV, the most
serious of which may lead to arbitrary code execution. This update
addresses the issues by updating ClamAV to version 0.96.1. ClamAV is
distributed only with Mac OS X Server systems. Further information is
available via the ClamAV website at http://www.clamav.net/

CoreGraphics
CVE-ID: CVE-2010-1801
Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8,
Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: Opening a maliciously crafted PDF file may lead to an
unexpected application termination or arbitrary code execution
Description: A heap buffer overflow exists in CoreGraphics' handling
of PDF files. Opening a maliciously crafted PDF file may lead to an
unexpected application termination or arbitrary code execution. This
issue is addressed through improved bounds checking. Credit to
Rodrigo Rubira Branco from the Check Point Vulnerability Discovery
Team (VDT) for reporting this issue.

libsecurity
CVE-ID: CVE-2010-1802
Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8,
Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: An attacker in a privileged network position who can obtain
a domain name that differs only in the last characters from the name
of a legitimate domain may impersonate hosts in that domain
Description: An issue exists in the handling of certificate host
names. For host names containing three or more components, the last
characters are not properly compared. In the case of a name
containing exactly three components, only the last character is not
checked. For example, if an attacker in a privileged network position
could obtain a certificate for www.example.con the attacker can
impersonate www.example.com. This issue is addressed through improved
handling of certificate host names. Credit to Peter Speck for
reporting this issue.

PHP
CVE-ID: CVE-2010-1205
Available for: Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: Loading a maliciously crafted PNG image may lead to an
unexpected application termination or arbitary code execution
Description: A buffer overflow exists in PHP's libpng library.
Loading a maliciously crafted PNG image may lead to an unexpected
application termination or arbitary code execution. This issue is
addressed by updating libpng within PHP to version 1.4.3. This issue

Available for: Mac OS X v10.5.8, Mac OS X Server v10.5.8,
Mac OS X v10.6.4, Mac OS X Server v10.6.4
Impact: An unauthenticated remote attacker may cause a denial of
service or arbitrary code execution
Description: A buffer overflow exists in Samba. An unauthenticated
remote attacker may cause a denial of service or arbitrary code
execution by sending a maliciously crafted packet. This issue is
