iceweasel - security update

Multiple security issues have been found in Iceweasel, Debian’s version
of the Mozilla Firefox web browser: Multiple memory safety errors, out of
bound reads, use-after-frees and other implementation errors may lead to
the execution of arbitrary code, information disclosure, denial of
service.

For the stable distribution (wheezy), these problems have been fixed in
version 24.4.0esr-1~deb7u2.

For the unstable distribution (sid), these problems have been fixed in
version 24.4.0esr-1.

We recommend that you upgrade your iceweasel packages.
