vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - python-pillow: Buffer overflow in image convert function (CVE-2021-34552)

  - Buffer overflow in the ImagingPcdDecode function in PcdDecode.c in Pillow before 3.1.1 and Python Imaging
    Library (PIL) 1.1.7 and earlier allows remote attackers to cause a denial of service (crash) via a crafted
    PhotoCD file. (CVE-2016-2533)

  - Pillow before 3.3.2 allows context-dependent attackers to obtain sensitive information by using the
    crafted image file approach, related to an Integer Overflow issue affecting the Image.core.map_buffer
    in map.c component. (CVE-2016-9189)

  - Pillow before 3.3.2 allows context-dependent attackers to execute arbitrary code by using the crafted
    image file approach, related to an Insecure Sign Extension issue affecting the ImagingNew in Storage.c
    component. (CVE-2016-9190)

  - In Pillow before 8.1.0, PcxDecode has a buffer over-read when decoding a crafted PCX file because the
    user-supplied stride value is trusted for buffer calculations. (CVE-2020-35653)

  - 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. 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. There is an out-of-bounds read in J2kDecode, in
    j2ku_gray_i. (CVE-2021-25288)

  - 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)

  - 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)

  - 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. 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 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)

  - path_getbbox in path.c in Pillow before 9.0.0 improperly initializes ImagePath.Path. (CVE-2022-22815)

  - In _imagingcms.c in Pillow before 10.3.0, a buffer overflow exists because strcpy is used instead of
    strncpy. (CVE-2024-28219)
