Mandriva Linux Security Advisory 2010-042 - Mozilla developers identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. 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. 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. 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. 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.

Hidetake Jo discovered that the showModalDialog in Firefox did not always honor the same-origin policy. An attacker could exploit this to run untrusted JavaScript from other domains. Georgi Guninski discovered that the same-origin check in Firefox could be bypassed by utilizing a crafted SVG image. If a user were tricked into viewing a malicious website, an attacker could exploit this to read data from other domains. Various other issues were also addressed.
