    Package        : libgd2
    CVE ID         : CVE-2016-3074
    Debian Bug     : 822242
    
    Hans Jerry Illikainen discovered that libgd2, a library for programmatic
    graphics creation and manipulation, suffers of a signedness
    vulnerability which may result in a heap overflow when processing
    specially crafted compressed gd2 data. A remote attacker can take
    advantage of this flaw to cause an application using the libgd2 library
    to crash, or potentially, to execute arbitrary code with the privileges
    of the user running the application.
    
    For the oldstable distribution (wheezy), this problem has been fixed
    in version 2.0.36~rc1~dfsg-6.1+deb7u2.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 2.1.0-5+deb8u1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.1.1-4.1.
    
    We recommend that you upgrade your libgd2 packages.
