Fedora 34: FEDORA-2022-473560d1a6 Critical: Lua DoS Fixes

Lua is a powerful light-weight programming language designed for

extending applications. Lua is also frequently used as a

general-purpose, stand-alone language. Lua is free software.

Lua combines simple procedural syntax with powerful data description

constructs based on associative arrays and extensible semantics. Lua

is dynamically typed, interpreted from bytecodes, and has automatic

memory management with garbage collection, making it ideal for

configuration, scripting, and rapid prototyping.

Update to lua 5.4.4, 5.3.6. Note that while this fixes CVE-2021-43519, it was

also fixed in 5.4.3-4. ---- Fix CVE-2021-44647 (and other known upstream bugs)

* Tue Feb 1 2022 Tom Callaway - 5.4.4-1

- update to 5.4.4, update bootstrap code to 5.3.6

- 5.4.4 contains the fix for 5.4.3 bug7, which is also CVE-2021-43519
