(GD: Multiple vulnerabilities)

    Xavier Roche discovered an infinite loop in the gdPngReadData()
    function when processing a truncated PNG file (CVE-2007-2756). An
    integer overflow has been discovered in the gdImageCreateTrueColor()
    function (CVE-2007-3472). An error has been discovered in the function
    gdImageCreateXbm() function (CVE-2007-3473). Unspecified
    vulnerabilities have been discovered in the GIF reader (CVE-2007-3474).
    An error has been discovered when processing a GIF image that has no
    global color map (CVE-2007-3475). An array index error has been
    discovered in the file gd_gif_in.c when processing images with an
    invalid color index (CVE-2007-3476). An error has been discovered in
    the imagearc() and imagefilledarc() functions when processing overly
    large angle values (CVE-2007-3477). A race condition has been
    discovered in the gdImageStringFTEx() function (CVE-2007-3478).
  
Impact :

    A remote attacker could exploit one of these vulnerabilities to cause a
    Denial of Service or possibly execute arbitrary code with the
    privileges of the user running GD.
  
Workaround :

    There is no known workaround at this time."
