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

  - The pm_mallocarray2 function in lib/util/mallocvar.c in
    Netpbm through 10.81.03 allows remote attackers to
    cause a denial of service (heap-based buffer over-read)
    via a crafted image file, as demonstrated by
    pbmmask.(CVE-2018-8975)

  - 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)

  - A null pointer dereference vulnerability was found in
    netpbm before 10.61. A maliciously crafted SVG file
    could cause the application to crash.(CVE-2017-2586)

  - 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)

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.");
