Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

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

  - Pillow before 8.1.2 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)

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

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

  - 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)

  - 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 a     BLP container, and thus an attempted memory allocation     can be very large. (CVE-2021-27921)

  - 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-2020-35655)

  - 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.(CVE-2021-28677)

  - 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-2021-28676)

  - An issue was discovered in Pillow before 8.2.0. There     is an out-of-bounds read in J2kDecode, in     j2ku_graya_la.(CVE-2021-25287)

  - An issue was discovered in Pillow before 8.2.0. For BLP     data, BlpImagePlugin did not properly check that reads     (after jumping to file offsets) returned data. This     could lead to a DoS where the decoder could be run a     large number of times on empty data.(CVE-2021-28678)

  - An issue was discovered in Pillow before 8.2.0. There     is an out-of-bounds read in J2kDecode, in     j2ku_gray_i.(CVE-2021-25288)

  - 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.(CVE-2021-28675)

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.

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2021:4149 advisory.

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