Several remote vulnerabilities have been discovered in the Icedove mail client, an unbranded version of the Thunderbird client. The Common Vulnerabilities and Exposures project identifies the following problems: Jesse Ruderman, Kai Engert, Martijn Wargers, Mats Palmgren and Paul Nickerson discovered crashes in the layout engine, which might allow the execution of arbitrary code. Carsten Book, Wesley Garland, Igor Bukanov, moz_bug_r_a4, shutdown, Philip Taylor and tgirmann discovered crashes in the JavaScript engine, which might allow the execution of arbitrary code. moz_bug_r_a4 and Boris Zbarsky discovered several vulnerabilities in JavaScript handling, which could allow privilege escalation. Gerry Eisenhaur and moz_bug_r_a4 discovered that a directory traversal vulnerability in chrome: URI handling could lead to information disclosure. David Bloom discovered a race condition in the image handling of designMode elements, which can lead to information disclosure and potentially the execution of arbitrary code. Michal Zalewski discovered that timers protecting security-sensitive dialogs (by disabling dialog elements until a timeout is reached) could be bypassed by window focus changes through JavaScript. The Mozilla products from the old stable distribution (sarge) are no longer supported with security updates.
