Security issues were identified and fixed in firefox 3.0.x and 3.5.x: Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes 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 . Security researcher Orlando Barrera II reported via TippingPoint"s Zero Day Initiative that Mozilla"s implementation of Web Workers contained an error in its handling of array data types when processing posted messages. This error could be used by an attacker to corrupt heap memory and crash the browser, potentially running arbitrary code on a victim"s computer . Security researcher Alin Rad Pop of Secunia Research reported that the HTML parser incorrectly freed used memory when insufficient space was available to process remaining input. Under such circumstances, memory occupied by in-use objects was freed and could later be filled with attacker-controlled text. These conditions could result in the execution or arbitrary code if methods on the freed objects were subsequently called . Security researcher Hidetake Jo of Microsoft Vulnerability Research reported that the properties set on an object passed to showModalDialog were readable by the document contained in the dialog, even when the document was from a different domain. This is a violation of the same-origin policy and could result in a website running untrusted JavaScript if it assumed the dialogArguments could not be initialized by another site. An anonymous security researcher, via TippingPoint"s Zero Day Initiative, also independently reported this issue to Mozilla . Mozilla security researcher Georgi Guninski reported that when a SVG document which is served with Content-Type: application/octet-stream is embedded into another document via an <embed> tag with type=image/svg+xml, the Content-Type is ignored and the SVG document is processed normally. A website which allows arbitrary binary data to be uploaded but which relies on Content-Type: application/octet-stream to prevent script execution could have such protection bypassed. An attacker could upload a SVG document containing JavaScript as a binary file to a website, embed the SVG document into a malicous page on another site, and gain access to the script environment from the SVG-serving site, bypassing the same-origin policy . Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers. Additionally, some packages which require so, have been rebuilt and are being provided as updates.
