Details:

USN-1430-1 fixed vulnerabilities in Firefox. This update provides the
corresponding fixes for Thunderbird.

Original advisory details:

 Bob Clary, Christian Holler, Brian Hackett, Bobby Holley, Gary Kwong,
 Hilary Hall, Honza Bambas, Jesse Ruderman, Julian Seward, and Olli Pettay
 discovered memory safety issues affecting Firefox. If the user were tricked
 into opening a specially crafted page, an attacker could exploit these to
 cause a denial of service via application crash, or potentially execute
 code with the privileges of the user invoking Firefox. (CVE-2012-0467,
 CVE-2012-0468)
 
 Aki Helin discovered a use-after-free vulnerability in XPConnect. An
 attacker could potentially exploit this to execute arbitrary code with the
 privileges of the user invoking Firefox. (CVE-2012-0469)
 
 Atte Kettunen discovered that invalid frees cause heap corruption in
 gfxImageSurface. If a user were tricked into opening a malicious Scalable
 Vector Graphics (SVG) image file, an attacker could exploit these to cause
 a denial of service via application crash, or potentially execute code with
 the privileges of the user invoking Firefox. (CVE-2012-0470)
 
 Anne van Kesteren discovered a potential cross-site scripting (XSS)
 vulnerability via multibyte content processing errors. With cross-site
 scripting vulnerabilities, if a user were tricked into viewing a specially
 crafted page, a remote attacker could exploit this to modify the contents,
 or steal confidential data, within the same domain. (CVE-2012-0471)
 
 Matias Juntunen discovered a vulnerability in Firefox's WebGL
 implementation that potentially allows the reading of illegal video memory.
 An attacker could possibly exploit this to cause a denial of service via
 application crash. (CVE-2012-0473)
 
 Jordi Chancel, Eddy Bordi, and Chris McGowen discovered that Firefox
 allowed the address bar to display a different website than the one the
 user was visiting. This could potentially leave the user vulnerable to
 cross-site scripting (XSS) attacks. With cross-site scripting
 vulnerabilities, if a user were tricked into viewing a specially crafted
 page, a remote attacker could exploit this to modify the contents, or steal
 confidential data, within the same domain. (CVE-2012-0474)
 
 Simone Fabiano discovered that Firefox did not always send correct origin
 headers when connecting to an IPv6 websites. An attacker could potentially
 use this to bypass intended access controls. (CVE-2012-0475)
 
 Masato Kinugawa discovered that cross-site scripting (XSS) injection is
 possible during the decoding of ISO-2022-KR and ISO-2022-CN character sets.
 With cross-site scripting vulnerabilities, if a user were tricked into
 viewing a specially crafted page, a remote attacker could exploit this to
 modify the contents, or steal confidential data, within the same domain.
 (CVE-2012-0477)
 
 It was discovered that certain images rendered using WebGL could cause
 Firefox to crash. If the user were tricked into opening a specially crafted
 page, an attacker could exploit this to cause a denial of service via
 application crash, or potentially execute code with the privileges of the
 user invoking Firefox. (CVE-2012-0478)
 
 Mateusz Jurczyk discovered an off-by-one error in the OpenType Sanitizer.
 If the user were tricked into opening a specially crafted page, an attacker
 could exploit this to cause a denial of service via application crash, or
 potentially execute code with the privileges of the user invoking Firefox.
 (CVE-2011-3062)
 
 Daniel Divricean discovered a defect in the error handling of JavaScript
 errors can potentially leak the file names and location of JavaScript files
 on a server. This could potentially lead to inadvertent information
 disclosure and a vector for further attacks. (CVE-2011-1187)
 
 Jeroen van der Gun discovered a vulnerability in the way Firefox handled
 RSS and Atom feeds. Invalid RSS or ATOM content loaded over HTTPS caused
 the location bar to be updated with the address of this content, while the
 main window still displays the previously loaded content. An attacker could
 potentially exploit this vulnerability to conduct phishing attacks.
 (CVE-2012-0479)
