By sending a maliciously crafted packet, an attacker on the local network can trigger the overflow which may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue by removing UPnP IGD support. This issue does not affect systems prior to Mac OS X v10.4.
PDFKit - Opening a maliciously crafted PDF file may lead to an unexpected application termination or arbitrary code execution
An integer underflow exists in Preview's handling of PDF files. By enticing a user to open a maliciously crafted PDF file, an attacker may trigger the issue which may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue by performing additional validation of PDF files. This issue does not affect systems prior to Mac OS X v10.4.
PHP - Multiple vulnerabilities in PHP 4.4.4
PHP is updated to version 4.4.7 to address several vulnerabilities. Further information is available via the PHP web site at
http://www.php.net.
Quartz Composer - Viewing a maliciously crafted Quartz Composer file may lead to an unexpected application termination or arbitrary code execution
An uninitialized object pointer vulnerability exists in the handling of Quartz Composer files. By enticing a user to view a maliciously crafted Quartz Composer file, an attacker may trigger the issue which may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue by performing proper initialization of object pointers. This issue does not affect systems prior to Mac OS X v10.4.
Samba - When Windows file sharing is enabled, an unauthenticated remote attacker may cause an unexpected application termination or arbitrary code execution
Multiple heap buffer overflows exist in the Samba daemon. By sending maliciously crafted MS-RPC requests, a remote attacker can trigger the overflow which may lead to arbitrary code execution. This update addresses the issue by performing additional validation of MS-RPC requests.
Samba - When Windows file sharing is enabled, an unauthenticated remote attacker may be able to execute arbitrary shell commands
A command injection vulnerability exists in the Samba daemon. By sending maliciously crafted MS-RPC requests, a remote attacker can trigger the command injection. This update addresses the issue by performing additional validation of MS-RPC requests. This issue does not affect the default Samba configuration.
Samba - When Windows file sharing is enabled, users may bypass file system quotas
An issue exists in Samba when a server process drops its privileges. This could allow the quota enforcement to be bypassed, and the file system quota to be exceeded. This update addresses the issue by properly dropping privileges. Credit to Mike Matz of Wyomissing Area School District for reporting this issue.
SquirrelMail - Multiple vulnerabilities in SquirrelMail 1.4.5
SquirrelMail is updated to version 1.4.10 to address several vulnerabilities, the most serious of which is cross-site scripting triggered by viewing HTML mail. Further information is available via the SquirrelMail web site at
http://www.SquirrelMail.org/
Tomcat - Multiple vulnerabilities in Tomcat
Tomcat is updated to version 4.1.36 to address several vulnerabilities, the most serious of which are cross-site scripting and information disclosure. Further information is available via the Tomcat site at

WebCore - Visiting a malicious website may allow Java applets to load and run even when Java is disabled
Description: Safari provides an "Enable Java" preference, which when unchecked should prevent the loading of Java applets. By default, Java applets are allowed to be loaded. Navigating to a maliciously crafted web page may allow a Java applet to be loaded without checking the preference. This update addresses the issue through a stricter check of the "Enable Java" preference. Credit to Scott Wilde for reporting this issue.
WebCore - Content may be injected into HTML comments leading to cross-site scripting attacks
An issue exists in WebCore when parsing comments inside an HTML title element. This can allow an attacker to insert scripts into a web page on sites which allow the page owner to enter HTML, but not scripts. This update addresses the issue by correctly parsing comments in title elements.
WebCore - Visiting a malicious website may lead to the disclosure of URL contents
A design issue in WebCore allows a popup window to read the URL that is currently being viewed in the parent window. By enticing a user to visit a maliciously crafted web page, an attacker can trigger the issue, which may lead to the disclosure of information via the URL contents. This update addresses the issue through an improved cross-domain security check. Credit to Secunia Research for reporting this issue.
WebCore - Visiting a malicious website may allow cross-site scripting
In Safari, properties of certain global objects are not cleared when navigating to a new URL within the same window. By enticing a user to visit a maliciously crafted web page, an attacker may trigger the issue which may lead to cross-site scripting. This update addresses the issue by properly clearing global objects.
WebKit - Look-alike characters in a URL could be used to masquerade a website
The International Domain Name (IDN) support and Unicode fonts embedded in Safari could be used to create a URL which contains look-alike characters. These could be used in a malicious web site to direct the user to a spoofed site that visually appears to be a legitimate domain. This update addresses the issue by through an improved domain name validity check.
WebKit - Viewing a maliciously crafted web page may lead to arbitrary code execution
Description: Heap buffer overflows exist in the Perl Compatible Regular Expressions (PCRE) library used by the JavaScript engine in Safari. By enticing a user to visit a maliciously crafted web page, an attacker may trigger the issue, which may lead to arbitrary code execution. This update addresses the issue by performing additional validation of JavaScript regular expressions.
