iceweasel - security update

Multiple security issues have been found in Iceweasel, Debian’s version
of the Mozilla Firefox web browser: Multiple memory safety errors,
buffer overflows, missing permission checks, out of bound reads,
use-after-frees and other implementation errors may lead to the
execution of arbitrary code, privilege escalation, cross-site scripting
or denial of service.

For the stable distribution (wheezy), these problems have been fixed in
version 24.5.0esr-1~deb7u1.

For the unstable distribution (sid), these problems have been fixed in
version 24.5.0esr-1.

We recommend that you upgrade your iceweasel packages.
