Products Affected Product Security, Mac OS X 10.5 Security Update 2009-002 / Mac OS X v10.5.7 * Apache CVE-ID: CVE-2008-2939 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11 Impact: Visiting a malicious website via a proxy may result in cross-site scripting Description: An input validation issue exists in Apache's handling of FTP proxy requests containing wildcard characters. Visiting a malicious website via an Apache proxy may result in a cross-site scripting attack. This update addresses the issue by applying the Apache patch for version 2.0.63. Further information is available via the Apache web site at http://httpd.apache.org/ Apache 2.0.x is only shipped with Mac OS X Server v10.4.x systems. Mac OS X v10.5.x and Mac OS X Server v10.5.x ship with Apache 2.2.x. * Apache CVE-ID: CVE-2008-2939 Available for: Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Visiting a malicious website via a proxy may result in cross-site scripting Description: An input validation issue exists in Apache 2.2.9's handling of FTP proxy requests containing wildcard characters. Visiting a malicious website via an Apache proxy may result in a cross-site scripting attack. This update addresses the issue by updating Apache to version 2.2.11. Further information is available via the Apache web site at http://httpd.apache.org/ * Apache CVE-ID: CVE-2008-0456 Available for: Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Web sites that allow users to control the name of a served file may be vulnerable to HTTP response injection Description: A request forgery issue exists in Apache. Apache does not escape filenames when negotiating the correct content type to send to a remote browser. A user who can publish files with specially crafted names to a web site can substitute their own response for any web page hosted on the system. This update addresses the issue by escaping filenames in content negotiation responses. * ATS CVE-ID: CVE-2009-0154 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Viewing or downloading a document containing a maliciously crafted embedded CFF font may lead to arbitrary code execution Description: A heap buffer overflow exists in Apple Type Services' handling of Compact Font Format (CFF) fonts. Viewing or downloading a document containing a maliciously crafted embedded CFF font may lead to arbitrary code execution. This update addresses the issue through improved bounds checking.

On systems using the DNS Security Extensions (DNSSEC) protocol, a maliciously crafted DSA certificate could bypass the validation, which may lead to a spoofing attack. By default, DNSSEC is not enabled. This update addresses the issue by updating BIND to version 9.3.6-P1 on Mac OS X v10.4, and version 9.4.3-P1 for Mac OS X v10.5 systems. Further information is available via the ISC web site at https://www.isc.org/ * CFNetwork CVE-ID: CVE-2009-0144 Available for: Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Applications that use CFNetwork may send secure cookies in unencrypted HTTP requests Description: An implementation issue exists in CFNetwork's parsing of Set-Cookie headers, which may result in certain cookies being unexpectedly sent over a non-encrypted connection. This issue affects non-RFC compliant Set-Cookie headers that are accepted for compatibility reasons. This may result in applications that use CFNetwork, such as Safari, sending sensitive information in unencrypted HTTP requests. This update addresses the issue through improved parsing of Set-Cookie headers. This issue does not affect systems prior to Mac OS X v10.5.

Credit: Apple. * enscript CVE-ID: CVE-2004-1184, CVE-2004-1185, CVE-2004-1186, CVE-2008-3863 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Multiple vulnerabilities in enscript Description: enscript is updated to version 1.6.4 to address several vulnerabilities, the most serious of which may lead to arbitrary code execution. Further information is available via the gnu web site at http://www.gnu.org/software/enscript/ * Flash Player plug-in CVE-ID: CVE-2009-0519, CVE-2009-0520, CVE-2009-0114 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Multiple vulnerabilities in Adobe Flash Player plug-in Description: Multiple issues exist in the Adobe Flash Player plug-in, the most serious of which may lead to arbitrary code execution when viewing a maliciously crafted web site. The issues are addressed by updating the Flash Player plug-in on Mac OS v10.5.x systems to version 10.0.22.87, and to version 9.0.159.0 on Mac OS X v10.4.11 systems. Further information is available via the Adobe web site at http://www.adobe.com/support/security/bulletins/apsb09-01.html * Help Viewer CVE-ID: CVE-2009-0942 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Accessing a maliciously crafted "help:" URL may lead to arbitrary code execution Description: Help Viewer loads Cascading Style Sheets referenced in URL parameters without validating that the referenced style sheets are located within a registered help book. A malicious "help:" URL may be used to invoke arbitrary AppleScript files, which may lead to arbitrary code execution. This update addresses the issue through improved validation of file system paths when loading stylesheets. Credit to Brian Mastenbrook for reporting this issue. * Help Viewer CVE-ID: CVE-2009-0943 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Accessing a maliciously crafted "help:" URL may lead to arbitrary code execution Description: Help Viewer does not validate that full paths to HTML documents are within registered help books.

A remote attacker with the ability to observe network traffic from an affected system may obtain the contents of AOL Instant Messenger conversations. This update addresses the issue by changing the behavior of iChat to always attempt to use SSL, and to use less secure channels only if the "Require SSL" preference is not enabled. This issue does not affect systems prior to Mac OS X v10.5, as they do not support SSL for iChat accounts. * International Components for Unicode CVE-ID: CVE-2009-0153 Available for: Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Maliciously crafted content may bypass website filters and result in cross-site scripting Description: An implementation issue exists in ICU's handling of certain character encodings. Using ICU to convert invalid byte sequences to Unicode may result in over-consumption, where trailing bytes are considered part of the original character. This may be leveraged by an attacker to bypass filters on websites that attempt to mitigate cross-site scripting. This update addresses the issue through improved handling of invalid byte sequences. This issue does not affect systems prior to Mac OS X v10.5. Credit to Chris Weber of Casaba Security for reporting this issue. * IPSec CVE-ID: CVE-2008-3651, CVE-2008-3652 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6 Impact: Multiple vulnerabilities in the racoon daemon may lead to a denial of service Description: Multiple memory leaks exist in the racoon daemon in ipsec-tools before 0.7.1, which may lead to a denial of service.
