Package        : iceweasel
CVE ID         : CVE-2015-4497 CVE-2015-4498

Multiple security issues have been found in Iceweasel, Debian's version
of the Mozilla Firefox web browser. The Common Vulnerabilities and
Exposures project identifies the following problems:

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
version 38.2.1esr-1.

We recommend that you upgrade your iceweasel packages.
