Amazon Linux 2 : jsoup (ALAS-2025-2813)

high Nessus Plugin ID 233713

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of jsoup installed on the remote host is prior to 1.16.1-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2025-2813 advisory.

jsoup is a Java library for working with HTML. Those using jsoup versions prior to 1.14.2 to parse untrusted HTML or XML may be vulnerable to DOS attacks. If the parser is run on user supplied input, an attacker may supply content that causes the parser to get stuck (loop indefinitely until cancelled), to complete more slowly than usual, or to throw an unexpected exception. This effect may support a denial of service attack. The issue is patched in version 1.14.2. There are a few available workarounds. Users may rate limit input parsing, limit the size of inputs based on system resources, and/or implement thread watchdogs to cap and timeout parse runtimes. (CVE-2021-37714)

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

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

Solution

Run 'yum update jsoup' to update your system.
