  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.

*

Credit to Brian Mastenbrook for reporting this issue.

*

  iChat

  CVE-ID: CVE-2009-0152

  Available for: Mac OS X v10.5 through v10.5.6, Mac OS X Server v10.5 through v10.5.6

  Impact: iChat AIM communications configured for SSL may downgrade to plaintext

  Description: iChat supports Secure Sockets Layer (SSL) for AOL Instant Messenger and Jabber accounts. iChat automatically disables SSL for AOL Instant Messenger accounts when it is unable to connect, and sends subsequent communications in plain text until SSL is manually re-enabled. 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.

  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.
