RHEL 8 : less (RHSA-2024:4256)

critical Nessus Plugin ID 201278

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for less.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2024:4256 advisory.

The less utility is a text file browser that resembles more, but allows users to move backwards in the file as well as forwards. Since less does not read the entire input file at startup, it also starts more quickly than ordinary text editors.

Security Fix(es):

* less: OS command injection (CVE-2024-32487)

* less: missing quoting of shell metacharacters in LESSCLOSE handling (CVE-2022-48624)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL less package based on the guidance in RHSA-2024:4256.
