Update Summary

USN-8732-1 addresses a Minetest vulnerability where specially crafted network traffic from an authenticated user could crash the server or run programs. On Ubuntu Server 24.04 LTS, update `minetest-server` to 5.6.1+dfsg+~1.9.0mt8+dfsg-4ubuntu0.1~esm1.

Update Details

Security

  • Minetest did not properly sanitize the Lua sandbox environment when using LuaJIT, allowing a malicious mod to escape the sandbox and execute arbitrary code with full file system access on the server.
  • An authenticated attacker could use specially crafted network traffic to compromise the server.

Hints

  • A standard system update will apply the fix.
  • For Ubuntu Server 24.04 LTS (noble), install minetest-server version 5.6.1+dfsg+~1.9.0mt8+dfsg-4ubuntu0.1~esm1.
