| Description: | Several remote vulnerabilities have been discovered in the Iceweasel web browser, an unbranded version of the Firefox browser. The Common Vulnerabilities and Exposures project identifies the following problems: Justin Schuh, Tom Cross and Peter Williams discovered a buffer overflow in the parser for UTF-8 URLs, which may lead to the execution of arbitrary code. moz_bug_r_a4 discovered that the same-origin check in nsXMLDocument::OnChannelRedirect() could by bypassed. moz_bug_r_a4 discovered that several vulnerabilities in feedWriter could lead to Chrome privilege escalation. Paul Nickerson discovered that an attacker could move windows during a mouse click, resulting in unwanted action triggered by drag-and-drop. moz_bug_r_a4 discovered a vulnerability which can result in Chrome privilege escalation through XPCNativeWrappers. moz_bug_r_a4 discovered a vulnerability which can result in Chrome privilege escalation through XPCNativeWrappers. Olli Pettay and moz_bug_r_a4 discovered a Chrome privilege escalation vulnerability in XSLT handling. Jesse Ruderman discovered a crash in the layout engine, which might allow the execution of arbitrary code. Igor Bukanov, Philip Taylor, Georgi Guninski and Antoine Labour discovered crashes in the Javascript engine, which might allow the execution of arbitrary code. Dave Reed discovered that some Unicode byte order marks are stripped from Javascript code before execution, which can result in code being executed, which were otherwise part of a quoted string. Gareth Heyes discovered that some Unicode surrogate characters are ignored by the HTML parser. Boris Zbarsky discovered that resource: URLs allow directory traversal when using URL-encoded slashes. Georgi Guninski discovered that resource: URLs could bypass local access restrictions. Billy Hoffman discovered that the XBM decoder could reveal uninitialised memory. |
