The remote host is affected by the vulnerability described in GLSA-202405-07 (HTMLDOC: Multiple Vulnerabilities)

  - Integer overflow in the htmldoc 1.9.11 and before may allow attackers to execute arbitrary code and cause     a denial of service that is similar to CVE-2017-9181. (CVE-2021-20308)

  - A flaw was found in htmldoc in v1.9.12. Double-free in function pspdf_export(),in ps-pdf.cxx may result in     a write-what-where condition, allowing an attacker to execute arbitrary code and denial of service.
    (CVE-2021-23158)

  - A flaw was found in htmldoc before v1.9.12. Heap buffer overflow in pspdf_prepare_outpages(), in ps-     pdf.cxx may lead to execute arbitrary code and denial of service. (CVE-2021-23165)

  - A flaw was found in htmldoc in v1.9.12 and before. Null pointer dereference in file_extension(),in file.c     may lead to execute arbitrary code and denial of service. (CVE-2021-23180)

  - A security issue was found in htmldoc v1.9.12 and before. A NULL pointer dereference in the function     image_load_jpeg() in image.cxx may result in denial of service. (CVE-2021-23191)

  - A flaw was found in htmldoc in v1.9.12 and prior. A stack buffer overflow in parse_table() in ps-pdf.cxx     may lead to execute arbitrary code and denial of service. (CVE-2021-23206)

  - A flaw was found in htmldoc in v1.9.12. Heap buffer overflow in pspdf_prepare_page(),in ps-pdf.cxx may     lead to execute arbitrary code and denial of service. (CVE-2021-26252)

  - A flaw was found in htmldoc in v1.9.12. Heap buffer overflow in render_table_row(),in ps-pdf.cxx may lead     to arbitrary code execution and denial of service. (CVE-2021-26259)

  - Null pointer dereference in the htmldoc v1.9.11 and before may allow attackers to execute arbitrary code     and cause a denial of service via a crafted html file. (CVE-2021-26948)

  - Buffer overflow vulnerability in write_node in htmldoc through 1.9.11 allows attackers to cause a denial     of service via htmldoc/htmldoc/html.cxx:588. (CVE-2021-33235)

  - Buffer Overflow vulnerability in write_header in htmldoc through 1.9.11 allows attackers to casue a denial     of service via /htmldoc/htmldoc/html.cxx:273. (CVE-2021-33236)

  - A stack-based buffer under-read in htmldoc before 1.9.12, allows attackers to cause a denial of service     via a crafted BMP image to image_load_bmp. (CVE-2021-40985)

  - A stack-based buffer overflow in image_load_bmp() in HTMLDOC <= 1.9.13 results in remote code execution if     the victim converts an HTML document linking to a crafted BMP file. (CVE-2021-43579)

  - A heap buffer overflow in image_set_mask function of HTMLDOC before 1.9.15 allows an attacker to write     outside the buffer boundaries. (CVE-2022-0137)

  - A vulnerability was found in htmldoc version 1.9.15 where the stack out-of-bounds read takes place in     gif_get_code() and occurs when opening a malicious GIF file, which can result in a crash (segmentation     fault). (CVE-2022-0534)

  - In HTMLDOC 1.9.14, an infinite loop in the gif_read_lzw function can lead to a pointer arbitrarily     pointing to heap memory and resulting in a buffer overflow. (CVE-2022-24191)

  - There is a vulnerability in htmldoc 1.9.16. In image_load_jpeg function image.cxx when it calls     malloc,'img->width' and 'img->height' they are large enough to cause an integer overflow. So, the malloc     function may return a heap blosmaller than the expected size, and it will cause a buffer overflow/Address     boundary error in the jpeg_read_scanlines function. (CVE-2022-27114)

  - A flaw was found in htmldoc commit 31f7804. A heap buffer overflow in the function pdf_write_names in ps-     pdf.cxx may lead to arbitrary code execution and Denial of Service (DoS). (CVE-2022-28085)

  - HTMLDoc v1.9.15 was discovered to contain a heap overflow via (write_header)     /htmldoc/htmldoc/html.cxx:273. (CVE-2022-34033)

  - HTMLDoc v1.9.12 and below was discovered to contain a heap overflow via e_node     htmldoc/htmldoc/html.cxx:588. (CVE-2022-34035)

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

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2700 advisory.
