    Debian Bug     : 849038
    
    A stack overflow vulnerability was discovered within the
    gdImageFillToBorder function in libgd2, a library for programmatic
    graphics creation and manipulation, triggered when invalid colors are
    used with truecolor images. A remote attacker can take advantage of this
    flaw to cause a denial-of-service against an application using the
    libgd2 library.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 2.1.0-5+deb8u8.
    
    For the testing distribution (stretch), this problem has been fixed
    in version 2.2.2-29-g3c2b605-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.2.2-29-g3c2b605-1.
