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

  - A memory allocation vulnerability was found in netpbm
    before 10.61. A maliciously crafted SVG file could
    cause the application to crash.(CVE-2017-2587)

  - tiffttopnm in netpbm 10.47.63 does not properly use the
    libtiff TIFFRGBAImageGet function, which allows remote
    attackers to cause a denial of service (out-of-bounds
    read and write) via a crafted tiff image file, related
    to transposing width and height values.(CVE-2017-5849)

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.");
