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

  - Integer overflow in io-ico.c in gdk-pixbuf allows
    context-dependent attackers to cause a denial of
    service (segmentation fault and application crash) via
    a crafted image entry offset in an ICO file, which
    triggers an out-of-bounds read, related to compiler
    optimizations.(CVE-2017-6312)

  - Integer underflow in the load_resources function in
    io-icns.c in gdk-pixbuf allows context-dependent
    attackers to cause a denial of service (out-of-bounds
    read and program crash) via a crafted image entry size
    in an ICO file.(CVE-2017-6313)

  - The make_available_at_least function in io-tiff.c in
    gdk-pixbuf allows context-dependent attackers to cause
    a denial of service (infinite loop) via a large TIFF
    file.(CVE-2017-6314)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
