Mozilla Firefox was updated to version 10 to fix bugs and security issues. MFSA 2012-01: Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs 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. In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products. References CVE-2012-0443: Ben Hawkes, Christian Holler, Honza Bombas, Jason Orendorff, Jesse Ruderman, Jan Odvarko, Peter Van Der Beken, and Bill McCloskey reported memory safety problems that were fixed in Firefox 10. CVE-2012-0442: Jesse Ruderman and Bob Clary reported memory safety problems that were fixed in both Firefox 10 and Firefox 3.6.26. MFSA 2012-02/CVE-2011-3670: For historical reasons Firefox has been generous in its interpretation of web addresses containing square brackets around the host. If this host was not a valid IPv6 literal address, Firefox attempted to interpret the host as a regular domain name. Gregory Fleischer reported that requests made using IPv6 syntax using XMLHttpRequest objects through a proxy may generate errors depending on proxy configuration for IPv6. The resulting error messages from the proxy may disclose sensitive data because Same-Origin Policy will allow the XMLHttpRequest object to read these error messages, allowing user privacy to be eroded. Firefox now enforces RFC 3986 IPv6 literal syntax and that may break links written using the non-standard Firefox-only forms that were previously accepted. This was fixed previously for Firefox 7.0, Thunderbird 7.0, and SeaMonkey 2.4 but only fixed in Firefox 3.6.26 and Thunderbird 3.1.18 during 2012. MFSA 2012-03/CVE-2012-0445: Alex Dvorov reported that an attacker could replace a sub-frame in another domain"s document by using the name attribute of the sub-frame as a form submission target. This can potentially allow for phishing attacks against users and violates the HTML5 frame navigation policy. Firefox 3.6 and Thunderbird 3.1 are not affected by this vulnerability MFSA 2012-04/CVE-2011-3659: Security researcher regenrecht reported via TippingPoint"s Zero Day Initiative that removed child nodes of nsDOMAttribute can be accessed under certain circumstances because of a premature notification of AttributeChildRemoved. This use-after-free of the child nodes could possibly allow for for remote code execution. MFSA 2012-05/CVE-2012-0446: Mozilla security researcher moz_bug_r_a4 reported that frame scripts bypass XPConnect security checks when calling untrusted objects. This allows for cross-site scripting attacks through web pages and Firefox extensions. The fix enables the Script Security Manager to force security checks on all frame scripts. Firefox 3.6 and Thunderbird 3.1 are not affected by this vulnerability MFSA 2012-06/CVE-2012-0447: Mozilla developer Tim Abraldes reported that when encoding images as image/vnd.microsoft.icon the resulting data was always a fixed size, with uninitialized memory appended as padding beyond the size of the actual image. This is the result of mImageBufferSize in the encoder being initialized with a value different than the size of the source image. There is the possibility of sensitive data from uninitialized memory being appended to a PNG image when converted fron an ICO format image. This sensitive data may then be disclosed in the resulting image. Firefox 3.6 and Thunderbird 3.1 are not affected by this vulnerability MFSA 2012-07/CVE-2012-0444: Security researcher regenrecht reported via TippingPoint"s Zero Day Initiative the possibility of memory corruption during the decoding of Ogg Vorbis files. This can cause a crash during decoding and has the potential for remote code execution. MFSA 2012-08/CVE-2012-0449: Security researchers Nicolas Gregoire and Aki Helin independently reported that when processing a malformed embedded XSLT stylesheet, Firefox can crash due to a memory corruption. While there is no evidence that this is directly exploitable, there is a possibility of remote code execution. MFSA 2012-09/CVE-2012-0450: magicant starmen reported that if a user chooses to export their Firefox Sync key the "Firefox Recovery Key.html" file is saved with incorrect permissions, making the file contents potentially readable by other users on Linux and OS X systems. Firefox 3.6 is not affected by this vulnerability.
