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 Ubuntu 16.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-5438-2 advisory.

    USN-5438-1 fixed a vulnerability in HTMLDOC. This update provides the corresponding update for Ubuntu     14.04 ESM and Ubuntu 16.04 ESM.



Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5438-1 advisory.

    It was discovered that HTMLDOC did not properly manage memory under certain circumstances. If a user were     tricked into opening a specially crafted HTML file, a remote attacker could possibly use this issue to     cause HTMLDOC to crash, resulting in a denial of service, or possibly execute arbitrary code.

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

  - HTMLDOC 1.9.7 allows a stack-based buffer overflow in the hd_strlcpy() function in string.c (when called     from render_contents in ps-pdf.cxx) via a crafted HTML document. (CVE-2019-19630)

  - 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)

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

A buffer overflow was discovered in HTMLDOC, a HTML processor that generates indexed HTML, PS, and PDF, which could potentially result in the execution of arbitrary code. In addition a number of crashes were addressed.
