Debian: DSA-3580-2 Critical: Iceweasel Buffer Overflow Risk

Multiple security issues have been found in Iceweasel, Debian's version
of the Mozilla Firefox web browser: Multiple memory safety errors and
buffer overflows may lead to the execution of arbitrary code or denial
of service.

For the oldstable distribution (wheezy), these problems have been fixed in
version 38.8.0esr-1~deb7u1.

For the stable distribution (jessie), these problems have been fixed in
version 38.8.0esr-1~deb8u1.

For the unstable distribution (sid), these problems have been fixed in
version 45.1.0esr-1 of the firefox-esr source package and version
46.0-1 of the firefox source package.

We recommend that you upgrade your iceweasel packages.
