    CVE ID         : CVE-2015-8472 CVE-2015-8540
    Debian Bug     : 807112 807694
    
    Several vulnerabilities have been discovered in the libpng PNG library.
    The Common Vulnerabilities and Exposures project identifies the
    following problems:
    
    CVE-2015-8472
    
        It was discovered that the original fix for CVE-2015-8126 was
        incomplete and did not detect a potential overrun by applications
        using png_set_PLTE directly. A remote attacker can take advantage of
        this flaw to cause a denial of service (application crash).
    
    CVE-2015-8540
    
        Xiao Qixue and Chen Yu discovered a flaw in the png_check_keyword
        function. A remote attacker can potentially take advantage of this
        flaw to cause a denial of service (application crash).
    
    For the oldstable distribution (wheezy), these problems have been fixed
    in version 1.2.49-1+deb7u2.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1.2.50-2+deb8u2.
    
    We recommend that you upgrade your libpng packages.
