CVE-2015-4497
Jean-Max Reymond and Ucha Gobejishvili discovered a use-after-free
vulnerability which occurs when resizing of a canvas element is
triggered in concert with style changes. A web page containing
malicious content can cause Iceweasel to crash, or potentially,
execute arbitrary code with the privileges of the user running
Iceweasel.
CVE-2015-4498
Bas Venis reported a flaw in the handling of add-ons installation. A
remote attacker can take advantage of this flaw to bypass the add-on
installation prompt and trick a user into installing an add-on from
a malicious source.
For the oldstable distribution (wheezy), these problems have been fixed
in version 38.2.1esr-1~deb7u1.
For the stable distribution (jessie), these problems have been fixed in
version 38.2.1esr-1~deb8u1.
For the unstable distribution (sid), these problems have been fixed in

We recommend that you upgrade your iceweasel packages.
