Safari 4.0

  • CFNetwork

    CVE-ID: CVE-2009-1704

    Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.7, Mac OS X Server v10.5.7, Windows XP or Vista

    Impact: Downloaded image files may be misidentified as HTML, leading to JavaScript execution without warning the user

    Description: Image files are 'safe' types that, once downloaded, are displayed by Safari without warning the user. An issue in Safari may cause it to be unable to identify the file type of certain local image files. In this case, Safari will examine the content of those files and may treat them as HTML. If a file contains JavaScript, it will be executed in the local context. For a downloaded file, this should not occur without first prompting the user. This issue is addressed by treating files of unknown type as generic binary data, and by correctly identifying the image file types known to have this issue. Credit to Sergio 'shadown' Alvarez of Recurity Labs GmbH for reporting this issue.

  • CFNetwork

    Available for: Windows XP or Vista

    Impact: Cookies set during a private browsing session may remain after private browsing ends

    Description: Safari's Private Browsing feature is designed to allow users to browse without leaving evidence of the browser session on disk. An implementation issue in Private Browsing may cause cookies to remain on disk after Private Browsing ends. This may result in an unexpected disclosure of sensitive information. This update addresses the issue by removing cookies from the alternate cookie store when private browsing is disabled, or Safari quits. This issue does not affect Mac OS X systems. Credit to Michael Hay of Beatnik Monkey Software for reporting this issue.

  • Safari

    CVE-ID: CVE-2009-1707

    Available for: Windows XP or Vista

    Impact: "Reset Safari" may not immediately remove website passwords from memory

    Description: After clicking the "Reset" button for "Reset saved names and passwords" in the "Reset Safari..." menu option, Safari may take up to 30 seconds to clear the passwords. A user with access to the system in that time window may be able to access the stored credentials. This issue is addressed by resolving the race condition that leads to the delay. This issue does not affect Mac OS X systems. Credit to Philippe Couturier of izypage.com, and Andrew Wellington of The Australian National University for reporting this issue.

  • Safari

    CVE-ID: CVE-2009-1708

    Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.7, Mac OS X Server v10.5.7, Windows XP or Vista

    Impact: Visiting a maliciously crafted website may lead to a cross-site scripting attack

    Description: WebKit ignores Unicode byte order mark sequences when parsing web pages. Certain websites and web content filters attempt to sanitize input by blocking specific HTML tags. This approach to filtering may be bypassed and lead to cross-site scripting when encountering maliciously-crafted HTML tags containing byte order mark sequences. This update addresses the issue through improved handling of byte order mark sequences. Credit to Chris Weber of Casaba Security, LLC for reporting this issue.

  • WebKit

  • WebKit

    CVE-ID: CVE-2009-1681

    Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.7, Mac OS X Server v10.5.7, Windows XP or Vista

    Impact: Interacting with a maliciously crafted website may result in unexpected actions on other sites

    Description: A design issue exists in the same-origin policy mechanism used to limit interactions between websites. This policy allows websites to load pages from third-party websites into a subframe. This frame may be positioned to entice the user to click a particular element within the frame, an attack referred to as "clickjacking". A maliciously crafted website may be able to manipulate a user into taking an unexpected action, such as initiating a purchase. This update addresses the issue through adoption of the industry-standard 'X-Frame-Options' extension header, that allows individual web pages to opt out of being displayed within a subframe.

  • WebKit

    CVE-ID: CVE-2009-1684

    Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.7, Mac OS X Server v10.5.7, Windows XP or Vista

    Impact: Visiting a maliciously crafted website may result in cross-site scripting

    Description: A cross-site scripting issue exists in the separation of JavaScript contexts.

    Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.7, Mac OS X Server v10.5.7, Windows XP or Vista

    Impact: Visiting a maliciously crafted website may lead to arbitrary code execution

    Description: A type conversion issue exists in WebKit's JavaScript exception handling. When an attempt is made to assign the exception to a variable that is declared as a constant, an object is cast to an invalid type, causing memory corruption. Visiting a maliciously crafted website may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue by ensuring that assignment in a const declaration writes to the variable object. Credit to Jesse Ruderman of Mozilla Corporation for reporting this issue.
