intl/uconv/util/nsUnicodeDecodeHelper.cpp in Mozilla Firefox before 3.6.7 and Thunderbird before 3.1.1 inserts a U+FFFD sequence into text in certain circumstances involving undefined positions, which might make it easier for remote attackers to conduct cross-site scripting (XSS) attacks via crafted 8-bit text.

This update brings Mozilla Firefox to the 3.6.8 security release.

It fixes following security bugs: MFSA 2010-34 / CVE-2010-1211 / CVE-2010-1212: 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.

MFSA 2010-35 / CVE-2010-1208: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in the DOM attribute cloning routine where under certain circumstances an event attribute node can be deleted while another object still contains a reference to it. This reference could subsequently be accessed, potentially causing the execution of attacker controlled memory.

MFSA 2010-36 / CVE-2010-1209: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an error in Mozilla's implementation of NodeIterator in which a malicious NodeFilter could be created which would detach nodes from the DOM tree while it was being traversed. The use of a detached and subsequently deleted node could result in the execution of attacker-controlled memory.

MFSA 2010-37 / CVE-2010-1214: Security researcher J23 reported via TippingPoint's Zero Day Initiative an error in the code used to store the names and values of plugin parameter elements. A malicious page could embed plugin content containing a very large number of parameter elements which would cause an overflow in the integer value counting them. This integer is later used in allocating a memory buffer used to store the plugin parameters. Under such conditions, too small a buffer would be created and attacker-controlled data could be written past the end of the buffer, potentially resulting in code execution.

MFSA 2010-38 / CVE-2010-1215: Mozilla security researcher moz_bug_r_a4 reported that when content script which is running in a chrome context accesses a content object via SJOW, the content code can gain access to an object from the chrome scope and use that object to run arbitrary JavaScript with chrome privileges.

Firefox 3.5 and other Mozilla products built from Gecko 1.9.1 were not affected by this issue.

MFSA 2010-39 / CVE-2010-2752: Security researcher J23 reported via TippingPoint's Zero Day Initiative that an array class used to store CSS values contained an integer overflow vulnerability. The 16 bit integer value used in allocating the size of the array could overflow, resulting in too small a memory buffer being created. When the array was later populated with CSS values data would be written past the end of the buffer potentially resulting in the execution of attacker-controlled memory.

MFSA 2010-40 / CVE-2010-2753: Security researcher regenrecht reported via TippingPoint's Zero Day Initiative an integer overflow vulnerability in the implementation of the XUL <tree> element's selection attribute. When the size of a new selection is sufficiently large the integer used in calculating the length of the selection can overflow, resulting in a bogus range being marked selected. When adjustSelection is then called on the bogus range the range is deleted leaving dangling references to the ranges which could be used by an attacker to call into deleted memory and run arbitrary code on a victim's computer.

MFSA 2010-41 / CVE-2010-1205: OUSPG researcher Aki Helin reported a buffer overflow in Mozilla graphics code which consumes image data processed by libpng. A malformed PNG file could be created which would cause libpng to incorrectly report the size of the image to downstream consumers. When the dimensions of such images are underreported, the Mozilla code responsible for displaying the graphic will allocate too small a memory buffer to contain the image data and will wind up writing data past the end of the buffer. This could result in the execution of attacker-controlled memory.

MFSA 2010-42 / CVE-2010-1213: Security researcher Yosuke Hasegawa reported that the Web Worker method importScripts can read and parse resources from other domains even when the content is not valid JavaScript. This is a violation of the same-origin policy and could be used by an attacker to steal information from other sites.

MFSA 2010-43 / CVE-2010-1207: Mozilla developer Vladimir Vukicevic reported that a canvas element can be used to read data from another site, violating the same-origin policy. The read restriction placed on a canvas element which has had cross-origin data rendered into it can be bypassed by retaining a reference to the canvas element's context and deleting the associated canvas node from the DOM.

MFSA 2010-44 / CVE-2010-1210: Security researcher O. Andersen reported that undefined positions within various 8 bit character encodings are mapped to the sequence U+FFFD which when displayed causes the immediately following character to disappear from the text run. This could potentially contribute to XSS problems on sites which expected extra characters to be present within strings being sanitized on the server.

MFSA 2010-45 / CVE-2010-1206: Google security researcher Michal Zalewski reported two methods for spoofing the contents of the location bar. The first method works by opening a new window containing a resource that responds with an HTTP 204 (no content) and then using the reference to the new window to insert HTML content into the blank document. The second location bar spoofing method does not require that the resource opened in a new window respond with 204, as long as the opener calls window.stop() before the document is loaded.
In either case a user could be mislead as to the correct location of the document they are currently viewing.

MFSA 2010-45 / CVE-2010-2751: Security researcher Jordi Chancel reported that the location bar could be spoofed to look like a secure page when the current document was served via plaintext. The vulnerability is triggered by a server by first redirecting a request for a plaintext resource to another resource behind a valid SSL/TLS certificate. A second request made to the original plaintext resource which is responded to not with a redirect but with JavaScript containing history.back() and history.forward() will result in the plaintext resource being displayed with valid SSL/TLS badging in the location bar. References

MFSA 2010-46 / CVE-2010-0654: Google security researcher Chris Evans reported that data can be read across domains by injecting bogus CSS selectors into a target site and then retrieving the data using JavaScript APIs. If an attacker can inject opening and closing portions of a CSS selector into points A and B of a target page, then the region between the two injection points becomes readable to JavaScript through, for example, the getComputedStyle() API.

MFSA 2010-47 / CVE-2010-2754: Security researcher Soroush Dalili reported that potentially sensitive URL parameters could be leaked across domains upon script errors when the script filename and line number is included in the error message.

MFSA 2010-48 / CVE-2010-2755: Mozilla developer Daniel Holbert reported that the fix to the plugin parameter array crash that was fixed in Firefox 3.6.7 caused a crash showing signs of memory corruption. In certain circumstances, properties in the plugin instance's parameter array could be freed prematurely leaving a dangling pointer that the plugin could execute, potentially calling into attacker-controlled memory.

USN-930-1 fixed vulnerabilities in Firefox and Xulrunner. This update provides the corresponding updates for Ubuntu 9.04 and 9.10, along with additional updates affecting Firefox 3.6.6.

Several flaws were discovered in the browser engine of Firefox. If a user were tricked into viewing a malicious site, a remote attacker could use this to crash the browser or possibly run arbitrary code as the user invoking the program. (CVE-2010-1208, CVE-2010-1209, CVE-2010-1211, CVE-2010-1212)
