Amazon Linux 2 : lynx (ALAS-2023-2145)

medium Nessus Plugin ID 178494

Language:

Synopsis

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

Description

The version of lynx installed on the remote host is prior to 2.8.9-4. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2145 advisory.

Lynx through 2.8.9 mishandles the userinfo subcomponent of a URI, which allows remote attackers to discover cleartext credentials because they may appear in SNI data. (CVE-2021-38165)

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 lynx' to update your system.
