iceweasel - arbitrary code execution

It was discovered that crashes in the Javascript engine of Iceweasel,
an unbranded version of the Firefox browser, could potentially lead to
the execution of arbitrary code.

For the stable distribution (etch), this problem has been fixed in
version 2.0.0.14-0etch1.

For the unstable distribution (sid), this problem has been fixed in
version 2.0.0.14-1.

We recommend that you upgrade your iceweasel package.
