Successful exploitation of these vulnerabilities may allow execution of arbitrary code. 3) A weakness is caused due to a design error within the focus handling and can potentially be exploited to trick a user into uploading arbitrary files. This is related to: SA25904 4) An error in the Javascript engine can be exploited to run Javascript code with "chrome" privileges. 5) An error in the Javascript engine can be exploited to bypass the same-origin policy via the "XMLDocument.load()" function. 6) An error exists in the handling of images when a user leaves a page, which uses "designMode" frames. This can be exploited to disclose the user's navigation history, forward navigation information, and to cause a memory corruption. Successful exploitation of this vulnerability may allow execution of arbitrary code. 7) A design error related to timer-enabled dialogs can be exploited to trick a user into unintentionally confirming a security dialog. 8) The problem is that Firefox follows "302" redirects for stylesheets and allows reading the target URL via "element.sheet.href". This can potentially be exploited to disclose sensitive URL parameters. The vulnerabilities are reported in versions prior to 2.0.0.12. SOLUTION: Update to version 2.0.0.12. http://www.mozilla.com/en-US/firefox/2.0.0.12/releasenotes/#download PROVIDED AND/OR DISCOVERED BY: The vendor credits: 1) Jesse Ruderman, Kai Engert, Martijn Wargers, Mats Palmgren, and Paul Nickerson 2) Carsten Book, Wesley Garland, Igor Bukanov, moz_bug_r_a4, shutdown, Philip Taylor, and tgirmann 3) hong and Gregory Fleisher 4) moz_bug_r_a4 and Boris Zbarsky 5) moz_bug_r_a4 6) David Bloom 7) Michal Zalewski 8) Martin Straka ORIGINAL ADVISORY: Mozilla Foundation: http://www.mozilla.org/security/announce/2008/mfsa2008-01.html http://www.mozilla.org/security/announce/2008/mfsa2008-02.html http://www.mozilla.org/security/announce/2008/mfsa2008-03.html http://www.mozilla.org/security/announce/2008/mfsa2008-05.html http://www.mozilla.org/security/announce/2008/mfsa2008-06.html http://www.mozilla.org/security/announce/2008/mfsa2008-08.html http://www.mozilla.org/security/announce/2008/mfsa2008-10.html OTHER REFERENCES: SA25904: http://secunia.com/advisories/25904/ ---------------------------------------------------------------------- About: This Advisory was delivered by Secunia as a free service to help everybody keeping their systems up to date against the latest vulnerabilities.
