RedHat: RHSA-2023-1211:01 Moderate: lua security update
Summary
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.
