Unspecified vulnerability in the browser engine in Mozilla Firefox 3.5.x before 3.5.3 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

From Red Hat Security Advisory 2009:1430 :

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. nspr provides the Netscape Portable Runtime (NSPR).

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 with the privileges of the user running Firefox. (CVE-2009-3070, CVE-2009-3071, CVE-2009-3072, CVE-2009-3074, CVE-2009-3075)

A use-after-free flaw was found in Firefox. An attacker could use this flaw to crash Firefox or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2009-3077)

A flaw was found in the way Firefox handles malformed JavaScript. A website with an object containing malicious JavaScript could execute that JavaScript with the privileges of the user running Firefox.
(CVE-2009-3079)

Descriptions in the dialogs when adding and removing PKCS #11 modules were not informative. An attacker able to trick a user into installing a malicious PKCS #11 module could use this flaw to install their own Certificate Authority certificates on a user's machine, making it possible to trick the user into believing they are viewing a trusted site or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2009-3076)

A flaw was found in the way Firefox displays the address bar when window.open() is called in a certain way. An attacker could use this flaw to conceal a malicious URL, possibly tricking a user into believing they are viewing a trusted site. (CVE-2009-2654)

A flaw was found in the way Firefox displays certain Unicode characters. An attacker could use this flaw to conceal a malicious URL, possibly tricking a user into believing they are viewing a trusted site. (CVE-2009-3078)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.14. 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 3.0.14, 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.

This update brings the Mozilla XULRunner engine to the 1.9.0.14 stable release.

It also fixes various security issues :

  - / CVE-2009-30 /. (MFSA 2009-47 / CVE-2009-3069 /     CVE-2009-3070 / CVE-2009-3071 / CVE-2009-3072 /     CVE-2009-3073)

  - Mozilla developers and community members identified and     fixed several stability bugs in the browser engine used     in Firefox and other Mozilla-based products. Some of     these crashes showed evidence of memory corruption under     certain circumstances and we presume that with enough     effort at least some of these could be exploited to run     arbitrary code. (CVE-2009-3075)

  - Mozilla security researcher Jesse Rudermanreported that     when security modules were added or removed via     pkcs11.addmodule or pkcs11.deletemodule, the resulting     dialog was not sufficiently informative. Without     sufficient warning, an attacker could entice a victim to     install a malicious PKCS11 module and affect the     cryptographic integrity of the victim's browser.
    Security researcher Dan Kaminsky reported that this     issue had not been fixed in Firefox 3.0 and that under     certain circumstances pkcs11 modules could be installed     from a remote location. Firefox 3.5 releases are not     affected. (MFSA 2009-48 / CVE-2009-3076)

  - An anonymous security researcher, via TippingPoint's     Zero Day Initiative, reported that the columns of a XUL     tree element could be manipulated in a particular way     which would leave a pointer owned by the column pointing     to freed memory. An attacker could potentially use this     vulnerability to crash a victim's browser and run     arbitrary code on the victim's computer. (MFSA 2009-49 /     CVE-2009-3077)

  - Security researcher Juan Pablo Lopez Yacubian reported     that the default Windows font used to render the     locationbar and other text fields was improperly     displaying certain Unicode characters with tall     line-height. In such cases the tall line-height would     cause the rest of the text in the input field to be     scrolled vertically out of view. An attacker could use     this vulnerability to prevent a user from seeing the URL     of a malicious site. Corrie Sloot also independently     reported this issue to Mozilla. (MFSA 2009-50 /     CVE-2009-3078)

  - Mozilla security researcher moz_bug_r_a4 reported that     the BrowserFeedWriter could be leveraged to run     JavaScript code from web content with elevated     privileges. Using this vulnerability, an attacker could     construct an object containing malicious JavaScript and     cause the FeedWriter to process the object, running the     malicious code with chrome privileges. Thunderbird does     not support the BrowserFeedWriter object and is not     vulnerable in its default configuration. Thunderbird     might be vulnerable if the user has installed any add-on     which adds a similarly implemented feature and then     enables JavaScript in mail messages. This is not the     default setting and we strongly discourage users from     running JavaScript in mail. (MFSA 2009-51 /     CVE-2009-3079)

Security issues were identified and fixed in firefox 3.0.x :

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.0.14 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2009-3069, CVE-2009-3070, CVE-2009-3071, CVE-2009-3072).

Multiple unspecified vulnerabilities in the JavaScript engine in Mozilla Firefox before 3.0.14 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2009-3073, CVE-2009-3074, CVE-2009-3075).

Mozilla Firefox before 3.0.14 does not properly implement certain dialogs associated with the (1) pkcs11.addmodule and (2) pkcs11.deletemodule operations, which makes it easier for remote attackers to trick a user into installing or removing an arbitrary PKCS11 module (CVE-2009-3076).

Mozilla Firefox before 3.0.14 does not properly manage pointers for the columns (aka TreeColumns) of a XUL tree element, which allows remote attackers to execute arbitrary code via a crafted HTML document, related to a dangling pointer vulnerability.
(CVE-2009-3077).

Visual truncation vulnerability in Mozilla Firefox before 3.0.14 allows remote attackers to trigger a vertical scroll and spoof URLs via unspecified Unicode characters with a tall line-height property (CVE-2009-3078).

Unspecified vulnerability in Mozilla Firefox before 3.0.14 allows remote attackers to execute arbitrary JavaScript with chrome privileges via vectors involving an object, the FeedWriter, and the BrowserFeedWriter (CVE-2009-3079).

This update provides the latest Mozilla Firefox 3.0.x to correct these issues.

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

Update to new upstream Firefox version 3.5.3, fixing multiple security issues detailed in the upstream advisories:

  - Multiple memory corruption vulnerabilities could potentially     allow arbitrary code execution. (MFSA 2009-47)

  - The columns of a XUL tree element can manipulated in     a way that leads to a dangling pointer.  A remote attacker     could exploit this to crash the browser, or execute     arbitrary code. (MFSA 2009-49)

  - A URL containing certain Unicode characters with tall     tall-line height is displayed incorrectly in the location bar.
    A remote attacker could use this to prevent a user from     seeing the full URL of a malicious website. (MFSA 2009-50)

  - A remote attacker can leverage 'BrowserFeedWriter' to     execute JavaScript code with Chrome privileges.
