According to the versions of the python-pillow package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - The package pillow 5.2.0 and before 8.3.2 are vulnerable to Regular Expression Denial of Service (ReDoS)     via the getrgb function. (CVE-2021-23437)

  - An issue was discovered in Pillow before 8.1.1. The PDF parser allows a regular expression DoS (ReDoS)     attack via a crafted PDF file because of a catastrophic backtracking regex. (CVE-2021-25292)

  - An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.
    (CVE-2021-25293)

  - Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass     controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c.
    (CVE-2021-34552)

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.

The remote Fedora 33 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2021-15845d3abe advisory.

  - In Pillow before 8.1.0, TiffDecode has a heap-based buffer overflow when decoding crafted YCbCr files     because of certain interpretation conflicts with LibTIFF in RGBA mode. (CVE-2020-35654)

  - An issue was discovered in Pillow before 8.1.1. TiffDecode has a heap-based buffer overflow when decoding     crafted YCbCr files because of certain interpretation conflicts with LibTIFF in RGBA mode. NOTE: this     issue exists because of an incomplete fix for CVE-2020-35654. (CVE-2021-25289)

  - An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is a negative-offset memcpy with an     invalid size. (CVE-2021-25290)

  - An issue was discovered in Pillow before 8.1.1. In TiffDecode.c, there is an out-of-bounds read in     TiffreadRGBATile via invalid tile boundaries. (CVE-2021-25291)

  - An issue was discovered in Pillow before 8.1.1. The PDF parser allows a regular expression DoS (ReDoS)     attack via a crafted PDF file because of a catastrophic backtracking regex. (CVE-2021-25292)

  - An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c.
    (CVE-2021-25293)

  - Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the     reported size of a contained image is not properly checked for a BLP container, and thus an attempted     memory allocation can be very large. (CVE-2021-27921)

  - Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the     reported size of a contained image is not properly checked for an ICNS container, and thus an attempted     memory allocation can be very large. (CVE-2021-27922)

  - Pillow before 8.1.1 allows attackers to cause a denial of service (memory consumption) because the     reported size of a contained image is not properly checked for an ICO container, and thus an attempted     memory allocation can be very large. (CVE-2021-27923)

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