"The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the
dla-3305 advisory.

  - stb stb_image.h 2.19, as used in catimg, Emscripten, and other products, has a heap-based buffer overflow
    in the stbi__out_gif_code function. (CVE-2018-16981)

  - A heap buffer overflow in the start_decoder function in stb_vorbis through 2019-03-04 allows an attacker
    to cause a denial of service or execute arbitrary code by opening a crafted Ogg Vorbis file.
    (CVE-2019-13217)

  - Division by zero in the predict_point function in stb_vorbis through 2019-03-04 allows an attacker to
    cause a denial of service by opening a crafted Ogg Vorbis file. (CVE-2019-13218)

  - A NULL pointer dereference in the get_window function in stb_vorbis through 2019-03-04 allows an attacker
    to cause a denial of service by opening a crafted Ogg Vorbis file. (CVE-2019-13219)

  - Use of uninitialized stack variables in the start_decoder function in stb_vorbis through 2019-03-04 allows
    an attacker to cause a denial of service or disclose sensitive information by opening a crafted Ogg Vorbis
    file. (CVE-2019-13220)

  - A stack buffer overflow in the compute_codewords function in stb_vorbis through 2019-03-04 allows an
    attacker to cause a denial of service or execute arbitrary code by opening a crafted Ogg Vorbis file.
    (CVE-2019-13221)

  - An out-of-bounds read of a global buffer in the draw_line function in stb_vorbis through 2019-03-04 allows
    an attacker to cause a denial of service or disclose sensitive information by opening a crafted Ogg Vorbis
    file. (CVE-2019-13222)

  - A reachable assertion in the lookup1_values function in stb_vorbis through 2019-03-04 allows an attacker
    to cause a denial of service by opening a crafted Ogg Vorbis file. (CVE-2019-13223)

  - Buffer overflow vulnerability in function stbi__extend_receive in stb_image.h in stb 2.26 via a crafted
    JPEG file. (CVE-2021-28021)

  - stb_image.h 2.27 has a heap-based buffer over in stbi__jpeg_load, leading to Information Disclosure or
    Denial of Service. (CVE-2021-37789)

  - An issue was discovered in stb stb_image.h 1.33 through 2.27. The HDR loader parsed truncated end-of-file
    RLE scanlines as an infinite sequence of zero-length runs. An attacker could potentially have caused
    denial of service in applications using stb_image by submitting crafted HDR files. (CVE-2021-42715)

  - stb_image.h v2.27 was discovered to contain an integer overflow via the function
    stbi__jpeg_decode_block_prog_dc. This vulnerability allows attackers to cause a Denial of Service (DoS)
    via unspecified vectors. (CVE-2022-28041)

  - stb_image.h v2.27 was discovered to contain an heap-based use-after-free via the function
    stbi__jpeg_huff_decode. (CVE-2022-28042)

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