Updated firefox packages that address several security issues, fix bugs, add numerous enhancements, and upgrade Firefox to version 3.6.4, are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

[Updated 25 June 2010] The original packages distributed with this erratum had a bug which could cause unintended dependencies to be installed when upgrading. We have updated the packages to correct this bug.

Mozilla Firefox is an open source web browser.

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-2010-1121, CVE-2010-1200, CVE-2010-1202, CVE-2010-1203)

A flaw was found in the way browser plug-ins interact. It was possible for a plug-in to reference the freed memory from a different plug-in, resulting in the execution of arbitrary code with the privileges of the user running Firefox. (CVE-2010-1198)

Several integer overflow 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-2010-1196, CVE-2010-1199)

A focus stealing flaw was found in the way Firefox handled focus changes. A malicious website could use this flaw to steal sensitive data from a user, such as usernames and passwords. (CVE-2010-1125)

A flaw was found in the way Firefox handled the 'Content-Disposition:
attachment' HTTP header when the 'Content-Type: multipart' HTTP header was also present. A website that allows arbitrary uploads and relies on the 'Content-Disposition: attachment' HTTP header to prevent content from being displayed inline, could be used by an attacker to serve malicious content to users. (CVE-2010-1197)

A flaw was found in the Firefox Math.random() function. This function could be used to identify a browsing session and track a user across different websites. (CVE-2008-5913)

A flaw was found in the Firefox XML document loading security checks.
Certain security checks were not being called when an XML document was loaded. This could possibly be leveraged later by an attacker to load certain resources that violate the security policies of the browser or its add-ons. Note that this issue cannot be exploited by only loading an XML document. (CVE-2010-0182)

For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.6.4. You can find a link to the Mozilla advisories in the References section of this erratum.

This erratum upgrades Firefox from version 3.0.19 to version 3.6.4.
Due to the requirements of Firefox 3.6.4, this erratum also provides a number of other updated packages, including esc, totem, and yelp.

This erratum also contains multiple bug fixes and numerous enhancements. Space precludes documenting these changes in this advisory. For details concerning these changes, refer to the Firefox Release Notes links in the References section of this erratum.

Important: Firefox 3.6.4 is not completely backwards-compatible with all Mozilla Add-ons and Firefox plug-ins that worked with Firefox 3.0.19. Firefox 3.6 checks compatibility on first-launch, and, depending on the individual configuration and the installed Add-ons and plug-ins, may disable said Add-ons and plug-ins, or attempt to check for updates and upgrade them. Add-ons and plug-ins may have to be manually updated.

All Firefox users should upgrade to these updated packages, which contain Firefox version 3.6.4. After installing the update, Firefox must be restarted for the changes to take effect.

From Red Hat Security Advisory 2010:0499 :

Updated SeaMonkey packages that fix several security issues are now available for Red Hat Enterprise Linux 3 and 4.

The Red Hat Security Response Team has rated this update as having critical security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

SeaMonkey is an open source web browser, email and newsgroup client, IRC chat client, and HTML editor.

Several flaws were found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2010-1200)

A flaw was found in the way browser plug-ins interact. It was possible for a plug-in to reference the freed memory from a different plug-in, resulting in the execution of arbitrary code with the privileges of the user running SeaMonkey. (CVE-2010-1198)

An integer overflow flaw was found in the processing of malformed web content. A web page containing malicious content could cause SeaMonkey to crash or, potentially, execute arbitrary code with the privileges of the user running SeaMonkey. (CVE-2010-1199)

A flaw was found in the way SeaMonkey processed mail attachments. A specially crafted mail message could cause SeaMonkey to crash.
(CVE-2010-0163)

A flaw was found in the way SeaMonkey handled the 'Content-Disposition: attachment' HTTP header when the 'Content-Type:
multipart' HTTP header was also present. A website that allows arbitrary uploads and relies on the 'Content-Disposition: attachment' HTTP header to prevent content from being displayed inline, could be used by an attacker to serve malicious content to users.
(CVE-2010-1197)

All SeaMonkey users should upgrade to these updated packages, which correct these issues. After installing the update, SeaMonkey must be restarted for the changes to take effect.

MFSA 2010-25 Re-use of freed object due to scope confusion

Mozilla Firefox was updated to version 3.5.10, fixing various bugs and security issues.

MFSA 2010-33 / CVE-2008-5913: Security researcher Amit Klein reported that it was possible to reverse engineer the value used to seed Math.random(). Since the pseudo-random number generator was only seeded once per browsing session, this seed value could be used as a unique token to identify and track users across different websites.

MFSA 2010-32 / CVE-2010-1197: Security researcher Ilja van Sprundel of IOActive reported that the Content-Disposition: attachment HTTP header was ignored when Content-Type: multipart was also present. This issue could potentially lead to XSS problems in sites that allow users to upload arbitrary files and specify a Content-Type but rely on Content-Disposition: attachment to prevent the content from being displayed inline.

MFSA 2010-31 / CVE-2010-1125: Google security researcher Michal Zalewski reported that focus() could be used to change a user's cursor focus while they are typing, potentially directing their keyboard input to an unintended location. This behaviour was also present across origins when content from one domain was embedded within another via an iframe. A malicious web page could use this behaviour to steal keystrokes from a victim while they were typing sensitive information such as a password.

MFSA 2010-30 / CVE-2010-1199: Security researcher Martin Barbella reported via TippingPoint's Zero Day Initiative that an XSLT node sorting routine contained an integer overflow vulnerability. In cases where one of the nodes to be sorted contained a very large text value, the integer used to allocate a memory buffer to store its value would overflow, resulting in too small a buffer being created. An attacker could use this vulnerability to write data past the end of the buffer, causing the browser to crash and potentially running arbitrary code on a victim's computer.

MFSA 2010-29 / CVE-2010-1196: Security researcher Nils of MWR InfoSecurity reported that the routine for setting the text value for certain types of DOM nodes contained an integer overflow vulnerability. When a very long string was passed to this routine, the integer value used in creating a new memory buffer to hold the string would overflow, resulting in too small a buffer being allocated. An attacker could use this vulnerability to write data past the end of the buffer, causing a crash and potentially running arbitrary code on a victim's computer.

MFSA 2010-28 / CVE-2010-1198: Microsoft Vulnerability Research reported that two plugin instances could interact in a way in which one plugin gets a reference to an object owned by a second plugin and continues to hold that reference after the second plugin is unloaded and its object is destroyed. In these cases, the first plugin would contain a pointer to freed memory which, if accessed, could be used by an attacker to execute arbitrary code on a victim's computer.

MFSA 2010-27 / CVE-2010-0183: Security researcher wushi of team509 reported that the frame construction process for certain types of menus could result in a menu containing a pointer to a previously freed menu item. During the cycle collection process, this freed item could be accessed, resulting in the execution of a section of code potentially controlled by an attacker.

MFSA 2010-26 / CVE-2010-1200 / CVE-2010-1201 / CVE-2010-1202 / CVE-2010-1203: Mozilla developers 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.

MFSA 2010-25 / CVE-2010-1121: A memory corruption flaw leading to code execution was reported by security researcher Nils of MWR InfoSecurity during the 2010 Pwn2Own contest sponsored by TippingPoint's Zero Day Initiative. By moving DOM nodes between documents Nils found a case where the moved node incorrectly retained its old scope. If garbage collection could be triggered at the right time then Firefox would later use this freed object. The contest winning exploit only affects Firefox 3.6 and not earlier versions. Updated (June 22, 2010): Firefox 3.5, SeaMonkey 2.0, and Thunderbird 3.0 based on earlier versions of the browser engine were patched just in case there is an alternate way of triggering the underlying flaw.

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.
