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.

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)
