Description:
Multiple vulnerabilities have been reported in Firefox, which can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting attacks, potentially disclose sensitive information, and compromise a user's system.
1) Some errors in the JavaScript engine where certain temporary variables are not properly protected may be exploited to execute arbitrary code via a user-defined method triggering garbage collection.
One of the vulnerabilities affects only version 1.5. The other affects version 1.5 and prior.
2) An error in the dynamic style handling can be exploited to reference freed memory by changing the style of an element from "position:relative" to "position:static".
Successful exploitation may allow execution of arbitrary code.
The vulnerability has been reported in version 1.5.
3) An error in the "QueryInterface" method of the Location and Navigator objects can be exploited to cause a memory corruption.
Successful exploitation allows execution of arbitrary code.
NOTE: Exploit code is publicly available.
The vulnerability has been reported in version 1.5.
4) An input validation error in the processing of the attribute name when calling "XULDocument.persist()" can be exploited to inject arbitrary XML and JavaScript code in "localstore.rdf", which will be executed with the permissions of the browser the next time the browser starts up again.
5) Some integer overflows in the E4X, SVG, and Canvas functionalities may be exploited to execute arbitrary code.
The vulnerabilities have been reported in version 1.5.
6) A boundary error in the "nsExpatDriver::ParseBuffer()" function in the XML parser may be exploited to disclose data on the heap.
The vulnerability does not affect version 1.0.
7) The internal "AnyName" object of the E4X functionality is not properly protected. This can be exploited to create a communication channel between two windows or frames having different domains.
This does not pose any direct risks and does not allow bypass of same-origin restrictions or disclosure of web content from other domains.
The vulnerability does not affect version 1.0.
Solution:
Update to versions 1.0.8 or 1.5.0.1.
