More information:

Several 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 web site 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.

• CVE-2011-3650

  Iceweasel does not properly handle JavaScript files that contain many functions, which allows user-assisted remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted file that is accessed by debugging APIs, as demonstrated by Firebug.

For the stable distribution (squeeze), these problems have been fixed in version 3.0.11-1+squeeze6.

For the testing distribution (wheezy) and the unstable distribution (sid), these problems have been fixed in version 3.1.15-1.

We recommend that you upgrade your icedove packages.
