Debian DSA-2297-1 : icedove - several vulnerabilities
Critical Nessus Plugin ID 55942
The remote Debian host is missing a security-related update.
Several vulnerabilities have been discovered in Icedove, an unbranded version of the Thunderbird mail/news client. - CVE-2011-0084 'regenrecht' discovered that incorrect pointer handling in the SVG processing code could lead to the execution of arbitrary code. - CVE-2011-2378 'regenrecht' discovered that incorrect memory management in DOM processing could lead to the execution of arbitrary code. - CVE-2011-2981 'moz_bug_r_a_4' discovered a Chrome privilege escalation vulnerability in the event handler code. - CVE-2011-2982 Gary Kwong, Igor Bukanov, Nils and Bob Clary discovered memory corruption bugs, which may lead to the execution of arbitrary code. - CVE-2011-2983 'shutdown' discovered an information leak in the handling of RegExp.input. - CVE-2011-2984 'moz_bug_r_a4' discovered a Chrome privilege escalation vulnerability. As indicated in the Lenny (oldstable) release notes, security support for the Icedove packages in the oldstable needed to be stopped before the end of the regular Lenny security maintenance life cycle. You are strongly encouraged to upgrade to stable or switch to a different mail client.
Upgrade the iceweasel packages. For the stable distribution (squeeze), this problem has been fixed in version 3.0.11-1+squeeze4.
