    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.
