"The remote host is affected by the vulnerability described in GLSA-202211-10 (Pillow: Multiple 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)

  - 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)

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

  - path_getbbox in path.c in Pillow before 9.0.0 has a buffer over-read during initialization of
    ImagePath.Path. (CVE-2022-22816)

  - PIL.ImageMath.eval in Pillow before 9.0.0 allows evaluation of arbitrary expressions, such as ones that
    use the Python exec method. A lambda expression could also be used, (CVE-2022-22817)

  - Pillow before 9.0.1 allows attackers to delete files because spaces in temporary pathnames are mishandled.
    (CVE-2022-24303)

  - Pillow before 9.2.0 performs Improper Handling of Highly Compressed GIF Data (Data Amplification).
    (CVE-2022-45198)

  - Pillow before 9.3.0 allows denial of service via SAMPLESPERPIXEL. (CVE-2022-45199)

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