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.
