Cross-site scripting (XSS) vulnerability in the MozSearch plugin implementation in Mozilla Firefox before 3.0.9 allows user-assisted remote attackers to inject arbitrary web script or HTML via a javascript: URI in the SearchForm element.

From Red Hat Security Advisory 2009:0436 :

Updated firefox packages that fix several security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having critical security impact by the Red Hat Security Response Team.

Mozilla Firefox is an open source Web browser. XULRunner provides the XUL Runtime environment for Mozilla Firefox.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code as the user running Firefox.
(CVE-2009-1302, CVE-2009-1303, CVE-2009-1304, CVE-2009-1305)

Several flaws were found in the way malformed web content was processed. A web page containing malicious content could execute arbitrary JavaScript in the context of the site, possibly presenting misleading data to a user, or stealing sensitive information such as login credentials. (CVE-2009-0652, CVE-2009-1306, CVE-2009-1307, CVE-2009-1308, CVE-2009-1309, CVE-2009-1310, CVE-2009-1312)

A flaw was found in the way Firefox saved certain web pages to a local file. If a user saved the inner frame of a web page containing POST data, the POST data could be revealed to the inner frame, possibly surrendering sensitive information such as login credentials.
(CVE-2009-1311)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.9. You can find a link to the Mozilla advisories in the References section of this errata.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.0.9, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

The remote host is affected by the vulnerability described in GLSA-201301-01 (Mozilla Products: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in Mozilla Firefox,       Thunderbird, SeaMonkey, NSS, GNU IceCat, and XULRunner. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to view a specially crafted web       page or email, possibly resulting in execution of arbitrary code or a       Denial of Service condition. Furthermore, a remote attacker may be able       to perform Man-in-the-Middle attacks, obtain sensitive information,       bypass restrictions and protection mechanisms, force file downloads,       conduct XML injection attacks, conduct XSS attacks, bypass the Same       Origin Policy, spoof URL&rsquo;s for phishing attacks, trigger a vertical       scroll, spoof the location bar, spoof an SSL indicator, modify the       browser&rsquo;s font, conduct clickjacking attacks, or have other unspecified       impact.
    A local attacker could gain escalated privileges, obtain sensitive       information, or replace an arbitrary downloaded file.
  Workaround :

    There is no known workaround at this time.

Several remote vulnerabilities have been discovered in the Iceweasel web browser, an unbranded version of the Firefox browser. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-3079     'moz_bug_r_a4' discovered that a programming error in     the FeedWriter module could lead to the execution of     JavaScript code with elevated privileges.

  - CVE-2009-1310     Prateek Saxena discovered a cross-site scripting     vulnerability in the MozSearch plugin interface.

Security vulnerabilities have been discovered in previous versions, and corrected in the latest Mozilla Firefox 3.x, version 3.0.10.
(CVE-2009-1302, CVE-2009-1303, CVE-2009-1304, CVE-2009-1305, CVE-2009-0652, CVE-2009-1306, CVE-2009-1307, CVE-2009-1308, CVE-2009-1309, CVE-2009-1310, CVE-2009-1311, CVE-2009-1312, CVE-2009-1313)

This update provides the latest Mozilla Firefox 3.x to correct these issues.

Additionally, some packages which require so, have been rebuilt and are being provided as updates.

Update :

The recent Mozilla Firefox update missed the Firefox language packs for Mandriva Linux 2009. This update provides them, fixing the issue.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several flaws were discovered in the browser engine. If a user were tricked into viewing a malicious website, a remote attacker could cause a denial of service or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2009-1302, CVE-2009-1303, CVE-2009-1304, CVE-2009-1305)

It was discovered that Firefox displayed certain Unicode characters which could be visually confused with punctuation in valid web addresses in the location bar. An attacker could exploit this to spoof the location bar, such as in a phishing attack. (CVE-2009-0652)

Several flaws were discovered in the way Firefox processed malformed URI schemes. If a user were tricked into viewing a malicious website, a remote attacker could execute arbitrary JavaScript or steal private data. (CVE-2009-1306, CVE-2009-1307, CVE-2009-1309, CVE-2009-1310, CVE-2009-1312)

Cefn Hoile discovered Firefox did not adequately protect against embedded third-party stylesheets. An attacker could exploit this to perform script injection attacks using XBL bindings. (CVE-2009-1308)

Paolo Amadini discovered that Firefox would submit POST data when reloading an inner frame of a web page. If a user were tricked into viewing a malicious website, a remote attacker could steal private data. (CVE-2009-1311).

The installed version of Firefox is earlier than 3.0.9. Such versions are potentially affected by the following security issues :
 - Multiple remote memory corruption vulnerabilities exist that can be exploited to execute arbitrary code in the context of the user running the affected application. (MFSA 2009-14)
 - A flaw may exist where Unicode box drawing characters are allowed in Internationalized Domain Names where they could be visually confused with punctuation used in valid web addresses. An attacker can leverage this to launch a phishing-type scam against a victim. (MFSA 2009-15)

 - When an Adobe Flash file is loaded via the 'view-source:' scheme, the Flash plugin misinterprets the origin of the content as localhost. An attacker can leverage this to launch cross-site request forgery attacks. It is also possible to exploit this to place cookie-like objects on victims' computers. (MFSA 2009-17)
 - A vulnerability exists that allows attackers to inject arbitrary scripts into sites via XBL bindings. This vulnerability requires the attacker to have the ability to embed third-party stylesheets into the site. (MFSA 2009-18)
 - Multiple remote code execution vulnerabilities exist caused by the creation of documents whose URI does not match the document's principle using XMLHttpRequest, as well as a flaw in the 'XPCNativeWrapper.ToString' '__proto__' coming from the wrong scope. (MFSA 2009-19)
 - A malicious MozSearch plugin could be created using a JavaScript: URI in the SearchForm value. An attacker can leverage this in order to inject code into arbitrary sites. (MFSA 2009-20)
 - An information disclosure vulnerability exists when saving the inner frame of a web page as a file when the outer page has POST data associated with it. (MFSA 2009-21)
 - A cross site scripting vulnerability exists when handling a Refresh header containing a JavaScript: URI. (MFSA 2009-22)" );
