"The remote NewStart CGSL host, running version MAIN 6.06, has libjpeg-turbo packages installed that are affected by
multiple vulnerabilities:

  - Libjpeg-turbo versions 2.0.91 and 2.0.90 is vulnerable to a denial of service vulnerability caused by a
    divide by zero when processing a crafted GIF image. (CVE-2021-20205)

  - Out of bounds read in libjpeg-turbo in Google Chrome prior to 94.0.4606.54 allowed a remote attacker to
    potentially exploit heap corruption via a crafted HTML page. (CVE-2021-37972)

  - The PPM reader in libjpeg-turbo through 2.0.90 mishandles use of tjLoadImage for loading a 16-bit binary
    PPM file into a grayscale buffer and loading a 16-bit binary PGM file into an RGB buffer. This is related
    to a heap-based buffer overflow in the get_word_rgb_row function in rdppm.c. (CVE-2021-46822)

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