1.54.1. RHSA-2010:0112: Critical security update
Important
This update has already been released (prior to the GA of this release) as the security errata RHSA-2010:0112
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.
A use-after-free flaw was found in Firefox. Under low memory conditions, visiting a web page containing malicious content could result in Firefox executing arbitrary code with the privileges of the user running Firefox. (CVE-2009-1571)
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-2010-0159, CVE-2010-0160)
Two flaws were found in the way certain content was processed. An attacker could use these flaws to create a malicious web page that could bypass the same-origin policy, or possibly run untrusted JavaScript. (CVE-2009-3988, CVE-2010-0162)
For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.18. 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 3.0.18, which corrects these issues. After installing the update, Firefox must be restarted for the changes to take effect.

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 with the privileges of the user running Firefox. (CVE-2009-3979, CVE-2009-3981, CVE-2009-3986)
A flaw was found in the Firefox NT Lan Manager (NTLM) authentication protocol implementation. If an attacker could trick a local user that has NTLM credentials into visiting a specially-crafted web page, they could send arbitrary requests, authenticated with the user's NTLM credentials, to other applications on the user's system. (CVE-2009-3983)
A flaw was found in the way Firefox displayed the SSL location bar indicator. An attacker could create an unencrypted web page that appears to be encrypted, possibly tricking the user into believing they are visiting a secure page. (CVE-2009-3984)
A flaw was found in the way Firefox displayed blank pages after a user navigates to an invalid address. If a user visits an attacker-controlled web page that results in a blank page, the attacker could inject content into that blank page, possibly tricking the user into believing they are viewing a legitimate page. (CVE-2009-3985)
For technical details regarding these flaws, refer to the Mozilla security advisories for Firefox 3.0.16. You can find a link to the Mozilla advisories in the References section of this errata.

1.54.3. RHSA-2009:1530: Critical security update
Important
This update has already been released (prior to the GA of this release) as the security errata RHSA-2009:1530
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).
A flaw was found in the way Firefox handles form history. A malicious web page could steal saved form data by synthesizing input events, causing the browser to auto-fill form fields (which could then be read by an attacker). (CVE-2009-3370)
A flaw was found in the way Firefox creates temporary file names for downloaded files. If a local attacker knows the name of a file Firefox is going to download, they can replace the contents of that file with arbitrary contents. (CVE-2009-3274)
A flaw was found in the Firefox Proxy Auto-Configuration (PAC) file processor. If Firefox loads a malicious PAC file, it could crash Firefox or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2009-3372)
A heap-based buffer overflow flaw was found in the Firefox GIF image processor. A malicious GIF image could crash Firefox or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2009-3373)
A heap-based buffer overflow flaw was found in the Firefox string to floating point conversion routines. A web page containing malicious JavaScript could crash Firefox or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2009-1563)
A flaw was found in the way Firefox handles text selection. A malicious website may be able to read highlighted text in a different domain (e.g. another website the user is viewing), bypassing the same-origin policy. (CVE-2009-3375)
A flaw was found in the way Firefox displays a right-to-left override character when downloading a file. In these cases, the name displayed in the title bar differs from the name displayed in the dialog body. An attacker could use this flaw to trick a user into downloading a file that has a file name or extension that differs from what the user expected. (CVE-2009-3376)
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-2009-3374, CVE-2009-3380, CVE-2009-3382)

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)
