CentOS 9 : lua-5.4.4-3.el9

critical Nessus Plugin ID 191333


The remote CentOS host is missing a security update for lua.


The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the lua-5.4.4-3.el9 build changelog.

- 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)

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


Update the CentOS 9 Stream lua package.
