"The remote host is affected by the vulnerability described in GLSA-201206-20
(gdk-pixbuf: Denial of Service)

    Two vulnerabilities have been found in gdk-pixbuf:
      The 'gdk_pixbuf__gif_image_load()' function in io-gif.c fails to
        properly handle certain return values from subroutines (CVE-2011-2485).
      The 'read_bitmap_file_data()' function in io-xbm.c contains an
        integer overflow error (CVE-2012-2370).
  
Impact :

    A remote attacker could entice a user to open a specially crafted image
      in an application linked against gdk-pixbuf, possibly resulting in Denial
      of Service.
  
Workaround :

    There is no known workaround at this time."

    Packages which depend on this library may need to be recompiled. Tools
