updates.");
  script_set_attribute(attribute:"description", value:
"According to the versions of the python-pillow package installed, the
EulerOS Virtualization installation on the remote host is affected by
the following vulnerabilities :

  - libImaging/FliDecode.c in Pillow before 6.2.2 has an
    FLI buffer overflow.(CVE-2020-5313)

  - An out-of-bounds write flaw was discovered in
    python-pillow in the way SGI RLE images are decoded. An
    application that uses python-pillow to decode untrusted
    images may be vulnerable to this flaw, which can allow
    an attacker to crash the application or potentially
    execute code on the system.(CVE-2020-5311)

  - libImaging/PcxDecode.c in Pillow before 6.2.2 has a PCX
    P mode buffer overflow.(CVE-2020-5312)

  - In libImaging/SgiRleDecode.c in Pillow through 7.0.0, a
    number of out-of-bounds reads exist in the parsing of
    SGI image files, a different issue than
    CVE-2020-5311.(CVE-2020-11538)

  - In libImaging/Jpeg2KDecode.c in Pillow before 7.1.0,
    there are multiple out-of-bounds reads via a crafted
    JP2 file.(CVE-2020-10994)

  - In libImaging/PcxDecode.c in Pillow before 7.1.0, an
    out-of-bounds read can occur when reading PCX files
    where state->shuffle is instructed to read beyond
    state->buffer.(CVE-2020-10378)

  - Pillow before 7.1.0 has multiple out-of-bounds reads in
    libImaging/FliDecode.c.(CVE-2020-10177)

  - libImaging/TiffDecode.c in Pillow before 6.2.2 has a
    TIFF decoding integer overflow, related to
    realloc.(CVE-2020-5310)

  - In Pillow before 7.1.0, there are two Buffer Overflows
    in libImaging/TiffDecode.c.(CVE-2020-10379)

  - There is a DoS vulnerability in Pillow before 6.2.2
    caused by FpxImagePlugin.py calling the range function
    on an unvalidated 32-bit integer if the number of bands
    is large. On Windows running 32-bit Python, this
    results in an OverflowError or MemoryError due to the 2
    GB limit. However, on Linux running 64-bit Python this
    results in the process being terminated by the OOM
    killer.(CVE-2019-19911)

  - ** RESERVED ** This candidate has been reserved by an
    organization or individual that will use it when
    announcing a new security problem. When the candidate
    has been publicized, the details for this candidate
    will be provided.(CVE-2020-19911)

  - In Pillow before 8.1.0, PcxDecode has a buffer
    over-read when decoding a crafted PCX file because the
    user-supplied stride value is trusted for buffer
    calculations.(CVE-2020-35653)

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.");
