"According to the versions of the gdk-pixbuf2 packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

  - An exploitable heap overflow vulnerability exists in
    the gdk_pixbuf__jpeg_image_load_increment functionality
    of Gdk-Pixbuf 2.36.6. A specially crafted jpeg file can
    cause a heap overflow resulting in remote code
    execution. An attacker can send a file or url to
    trigger this vulnerability.i1/4^CVE-2017-2862i1/4%0

  - An exploitable integer overflow vulnerability exists in
    the tiff_image_parse functionality of Gdk-Pixbuf 2.36.6
    when compiled with Clang. A specially crafted tiff file
    can cause a heap-overflow resulting in remote code
    execution. An attacker can send a file or a URL to
    trigger this vulnerability.i1/4^CVE-2017-2870i1/4%0

  - Gnome gdk-pixbuf 2.36.8 and older is vulnerable to
    several integer overflow in the gif_get_lzw function
    resulting in memory corruption and potential code
    executioni1/4^CVE-2017-1000422i1/4%0
