SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral vulnerabilities have been discovered in Icedove, a mail client based on Thunderbird.
- CVE-2011-3647 The JSSubScriptLoader does not properly handle XPCNativeWrappers during calls to the loadSubScript method in an add-on, which makes it easier for remote attackers to gain privileges via a crafted website that leverages certain unwrapping behavior.
- CVE-2011-3648 A cross-site scripting (XSS) vulnerability allows remote attackers to inject arbitrary web script or HTML via crafted text with Shift JIS encoding.
SolutionUpgrade the icedove packages.
For the stable distribution (squeeze), these problems have been fixed in version 3.0.11-1+squeeze6.
