[GLSA-200505-11] Mozilla Suite, Mozilla Firefox: Remote compromise |
||
Mozilla Suite, Mozilla Firefox: Remote compromise Detailed Explanation for this Vulnerability Assessment The remote host is affected by the vulnerability described in GLSA-200505-11 (Mozilla Suite, Mozilla Firefox: Remote compromise) The Mozilla Suite and Firefox do not properly protect "IFRAME" JavaScript URLs from being executed in context of another URL in the history list (CVE-2005-1476). The Mozilla Suite and Firefox also fail to verify the "IconURL" parameter of the "InstallTrigger.install()" function (CVE-2005-1477). Michael Krax and Georgi Guninski discovered that it is possible to bypass JavaScript-injection security checks by wrapping the javascript: URL within the view-source: or jar: pseudo-protocols (MFSA2005-43). Impact A malicious remote attacker could use the "IFRAME" issue to execute arbitrary JavaScript code within the context of another website, permiting to steal cookies or other sensitive data. By supplying a javascript: URL as the "IconURL" parameter of the "InstallTrigger.Install()" function, a remote attacker could also execute arbitrary JavaScript code. Combining both vulnerabilities with a website which is permited to install software or wrapping javascript: URLs within the view-source: or jar: pseudo-protocols could possibly lead to the execution of arbitrary code with user rights. Workaround Affected systems can be protected by disabling JavaScript. However, we encourage Mozilla Suite or Mozilla Firefox users to upgrade to the latest available version.
