The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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 Nessus relies on the presence of the package as reported by the vendor.

    CVE-2020-11538:
    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-2020-35655:
    In Pillow before 8.1.0, SGIRleDecode has a 4-byte buffer over-read when decoding crafted SGI RLE image     files because offsets and length tables are mishandled.

    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 a BLP container, and thus an attempted     memory allocation can be very large.

    CVE-2021-27923:
    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-2021-28676:
    An issue was discovered in Pillow before 8.2.0. For FLI data, FliDecode did not properly check that the     block advance was non-zero, potentially leading to an infinite loop on load.

    CVE-2021-25293:
    An issue was discovered in Pillow before 8.1.1. There is an out-of-bounds read in SGIRleDecode.c. A flaw     was found in python-pillow. There is an Out of Bounds Read in SGIRleDecode.c.

    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 ICNS container, and thus an attempted     memory allocation can be very large. A flaw was found in python-pillow. Attackers can 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.

    An issue was discovered in Pillow before 8.2.0. PSDImagePlugin.PsdImageFile lacked a sanity check on the     number of input layers relative to the size of the data block. This could lead to a DoS on Image.open     prior to Image.load. A flaw was found in python-pillow. PsdImagePlugin.PsdImageFile does not sanity check     the number of input layers with regard to the size of the data block which could lead to a denial-of-     service.

    CVE-2021-28677     An issue was discovered in Pillow before 8.2.0. For EPS data, the readline implementation used in     EPSImageFile has to deal with any combination of \r and \n as line endings. It used an accidentally     quadratic method of accumulating lines while looking for a line ending. A malicious EPS file could use     this to perform a DoS of Pillow in the open phase, before an image was accepted for opening. A flaw was     found in python-pillow. The readline used in EPS has to deal with any combination of \r and \n as line     endings. It accidentally used a quadratic method of accumulating lines while looking for a line ending.
