Package        : icedove
Vulnerability  : several
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2011-3670 CVE-2012-0442 CVE-2012-0444 CVE-2012-0449

Several vulnerabilities have been discovered in Icedove, Debian's
variant of the Mozilla Thunderbird code base.

CVE-2011-3670
       Icedove does not not properly enforce the IPv6 literal address
       syntax, which allows remote attackers to obtain sensitive
       information by making XMLHttpRequest calls through a proxy and
       reading the error messages.

CVE-2012-0442
       Memory corruption bugs could cause Icedove to crash or
       possibly execute arbitrary code.

CVE-2012-0444
       Icedove does not properly initialize nsChildView data
       structures, which allows remote attackers to cause a denial of
       service (memory corruption and application crash) or possibly
       execute arbitrary code via a crafted Ogg Vorbis file.

CVE-2012-0449
       Icedove allows remote attackers to cause a denial of service
       (memory corruption and application crash) or possibly execute
       arbitrary code via a malformed XSLT stylesheet that is
       embedded in a document

For the stable distribution (squeeze), this problem has been fixed in
version 3.0.11-1+squeeze7.

We recommend that you upgrade your icedove packages.
