"The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has python-pillow packages installed that are
affected by multiple vulnerabilities:

  - An issue was discovered in Pillow before 6.2.0. When
    reading specially crafted invalid image files, the
    library can either allocate very large amounts of memory
    or take an extremely long period of time to process the
    image. (CVE-2019-16865)

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
