The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 24.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7225-1 advisory.

    It was discovered that HTMLDOC incorrectly handled memory in the image_set_mask, git_read_lzw,     write_header and write_node functions, which could lead to a heap buffer overflow. An attacker could     possibly use this issue to cause a denial of service or execute arbitrary code. This issue only affected     Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2022-0137, CVE-2022-24191,     CVE-2022-34033, CVE-2022-34035)

    It was discovered that HTMLDOC incorrectly handled memory in the gif_get_code function, which could lead     to a segmentation fault. If a user or application were tricked into opening a crafted GIF file, an     attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 14.04     LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2022-0534)

    It was discovered that HTMLDOC did not perform proper bounds checks on image dimensions when loading JPEG     images, which could lead to a buffer overflow. If a user or application were tricked into opening a     crafted JPEG image, an attacker could possibly use this issue to cause a denial of service. This issue     only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS.
    (CVE-2022-27114)

    It was discovered that HTMLDOC incorrectly handled memory in the pdf_write_names function, which could     lead to a heap buffer overflow. If a user or application were tricked into opening a specially crafted     file, an attacker could possibly use this issue to cause a denial of service or leak sensitive     information. This issue only affected Ubuntu 14.04 LTS, Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04     LTS and Ubuntu 22.04 LTS. (CVE-2022-28085)

    It was discovered that HTMLDOC could be made to write out of bounds when attempting to strip whitespace.
    An attacker could use this issue to cause a denial of service or execute arbitrary code. (CVE-2024-45508)

    It was discovered that HTMLDOC incorrectly handled memory in the parse_pre function, which could lead to a     heap buffer overflow. If a user or application were tricked into opening a specially crafted file, an     attacker could possibly use this issue to cause a denial of service or execute arbitrary code.
    (CVE-2024-46478)

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

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

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)
