Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2928 advisory.

- Buffer overflow vulnerability 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 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)

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

Solution

Upgrade the htmldoc packages.

For Debian 9 stretch, these problems have been fixed in version 1.8.27-8+deb9u2.
