The remote Rocky Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:0957 advisory.

  - Stack overflow in lua_resume of ldo.c in Lua Interpreter 5.1.0~5.4.4 allows attackers to perform a Denial     of Service via a crafted script file. (CVE-2021-43519)

  - Use after free in garbage collector and finalizer of lgc.c in Lua interpreter 5.4.0~5.4.3 allows attackers     to perform Sandbox Escape via a crafted script file. (CVE-2021-44964)

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

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)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-176 advisory.

  - Stack overflow in lua_resume of ldo.c in Lua Interpreter 5.1.0~5.4.4 allows attackers to perform a Denial     of Service via a crafted script file. (CVE-2021-43519)

  - Lua v5.4.3 and above are affected by SEGV by type confusion in funcnamefromcode function in ldebug.c which     can cause a local denial of service. (CVE-2021-44647)

  - singlevar in lparser.c in Lua from (including) 5.4.0 up to (excluding) 5.4.4 lacks a certain     luaK_exp2anyregup call, leading to a heap-based buffer over-read that might affect a system that compiles     untrusted Lua code. (CVE-2022-28805)

  - An issue in the component luaG_runerror of Lua v5.4.4 and below leads to a heap-buffer overflow when a     recursive error occurs. (CVE-2022-33099)
