USN-1222-1 fixed vulnerabilities in Firefox. This update provides updated packages for use with Firefox 7.

Benjamin Smedberg, Bob Clary, Jesse Ruderman, Bob Clary, Andrew McCreight, Andreas Gal, Gary Kwong, Igor Bukanov, Jason Orendorff, Jesse Ruderman, and Marcia Knous discovered multiple memory vulnerabilities in the browser rendering engine. An attacker could use these to possibly execute arbitrary code with the privileges of the user invoking Firefox. (CVE-2011-2995, CVE-2011-2997)

Boris Zbarsky discovered that a frame named 'location' could shadow the window.location object unless a script in a page grabbed a reference to the true object before the frame was created. This is in violation of the Same Origin Policy. A malicious website could possibly use this to access another website or the local file system. (CVE-2011-2999)

Ian Graham discovered that when multiple Location headers were present, Firefox would use the second one resulting in a possible CRLF injection attack. CRLF injection issues can result in a wide variety of attacks, such as XSS (Cross-Site Scripting) vulnerabilities, browser cache poisoning, and cookie theft. (CVE-2011-3000)

Mariusz Mlynski discovered that if the user could be convinced to hold down the enter key, a malicious website could potential pop up a download dialog and the default open action would be selected or lead to the installation of an arbitrary add-on. This would result in potentially malicious content being run with privileges of the user invoking Firefox. (CVE-2011-2372, CVE-2011-3001)

Michael Jordon and Ben Hawkes discovered flaws in WebGL. If a user were tricked into opening a malicious page, an attacker could cause the browser to crash. (CVE-2011-3002, CVE-2011-3003)

It was discovered that Firefox did not properly free memory when processing ogg files. If a user were tricked into opening a malicious page, an attacker could cause the browser to crash. (CVE-2011-3005)

David Rees and Aki Helin discovered a problems in the JavaScript engine. An attacker could exploit this to crash the browser or potentially escalate privileges within the browser. (CVE-2011-3232).

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

Security issues were identified and fixed in mozilla firefox and thunderbird :

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent the starting of a download in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted website (CVE-2011-2372).

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2011-2995).

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors (CVE-2011-2997).

Mozilla Firefox before 3.6.23 and 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not properly handle HTTP responses that contain multiple Location, Content-Length, or Content-Disposition headers, which makes it easier for remote attackers to conduct HTTP response splitting attacks via crafted header values (CVE-2011-3000).

Mozilla Firefox 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 do not prevent manual add-on installation in response to the holding of the Enter key, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted web site that triggers an unspecified internal error (CVE-2011-3001).

Use-after-free vulnerability in Mozilla Firefox 4.x through 6, Thunderbird before 7.0, and SeaMonkey before 2.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted OGG headers in a .ogg file (CVE-2011-3005).

YARR, as used in Mozilla Firefox before 7.0, Thunderbird before 7.0, and SeaMonkey before 2.4, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted JavaScript (CVE-2011-3232).

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.
