  script_tag(name:"insight", value:"Multiple vulnerabilities has been discovered and corrected in libpng:

  The png_format_buffer function in pngerror.c in libpng allows
  remote attackers to cause a denial of service (application crash)
  via a crafted PNG image that triggers an out-of-bounds read during
  the copying of error-message data.  NOTE: this vulnerability exists
  because of a CVE-2004-0421 regression (CVE-2011-2501).

  Buffer overflow in libpng, when used by an application that calls the
  png_rgb_to_gray function but not the png_set_expand function, allows
  remote attackers to overwrite memory with an arbitrary amount of data,
  and possibly have unspecified other impact, via a crafted PNG image
  (CVE-2011-2690).

  The png_err function in pngerror.c in libpng makes a function call
  using a NULL pointer argument instead of an empty-string argument,
  which allows remote attackers to cause a denial of service (application
  crash) via a crafted PNG image (CVE-2011-2691). NOTE: This does not
  affect the binary packages in Mandriva, but could affect users if
  PNG_NO_ERROR_TEXT is defined using the libpng-source-1.?.?? package.

  The png_handle_sCAL function in pngrutil.c in libpng does not properly
  handle invalid sCAL chunks, which allows remote attackers to cause
  a denial of service (memory corruption and application crash) or
  possibly have unspecified other impact via a crafted PNG image that
  triggers the reading of uninitialized memory (CVE-2011-2692).

  The updated packages have been patched to correct these issues.");
