HTMLDOC vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.10
- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in htmldoc.

Software Description:
- htmldoc: HTML processor that generates indexed HTML, PS, and PDF

Details:

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)
