RHEL 9 : lua (RHSA-2023:1211)

medium Nessus Plugin ID 172546

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:1211 advisory.

 The lua packages provide support for Lua, a powerful light-weight programming language designed for extending applications. Lua is also frequently used as a general-purpose, stand-alone language.

 The following packages have been upgraded to a later upstream version: lua (5.4.4).

 Security Fix(es):

 * lua: use after free allows Sandbox Escape (CVE-2021-44964)

 * lua: stack overflow in lua_resume of ldo.c allows a DoS via a crafted script file (CVE-2021-43519)

 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 lua package based on the guidance in RHSA-2023:1211.
