"Multiple vulnerabilities have been identified in libgd2, a library for
programmatic graphics creation and manipulation. The Common
Vulnerabilities and Exposures project identifies the following
problems :

  - CVE-2007-2445
    Grayscale PNG files containing invalid tRNS chunk CRC
    values could cause a denial of service (crash), if a
    maliciously crafted image is loaded into an application
    using libgd.

  - CVE-2007-3476
    An array indexing error in libgd's GIF handling could
    induce a denial of service (crash with heap corruption)
    if exceptionally large color index values are supplied
    in a maliciously crafted GIF image file.

  - CVE-2007-3477
    The imagearc() and imagefilledarc() routines in libgd
    allow an attacker in control of the parameters used to
    specify the degrees of arc for those drawing functions
    to perform a denial of service attack (excessive CPU
    consumption).

  - CVE-2007-3996
    Multiple integer overflows exist in libgd's image
    resizing and creation routines; these weaknesses allow
    an attacker in control of the parameters passed to those
    routines to induce a crash or execute arbitrary code
    with the privileges of the user running an application
    or interpreter linked against libgd2."
