Counter-Strike and Half-Life 1 Engine Updates

Steam has announced updates to Counter-Strike and the Half-Life 1 Engine to fix minor bugs as well as adding support for the VAC2 anti-cheat. Click on read more to view specific changes.

Half-Life 1: Engine

  • Servers will default to starting up using VAC2
  • Added “sv_uploadmax” cvar to limit the max size (in MB) a client can use for a custom resource (i.e spray decals)
  • Added “-sport” command line option to allow you to specify the VAC2 port the server should use
  • Don’t allow servers to execute “alias” commands on clients (prevents an infinite loop exploit using alias commands from servers)
  • Fixed S2C_CONNREJECT packet exploit causing the game to quit from any currently connected game server (found by Gavin Cotter)
  • Fixed crash exploit caused by specially crafted packet triggering a crash in the resource upload code (found by Gavin Cotter)
  • Fixed infinite loop in richtext/textentry control caused by large sets of spaces between words wrapping around line ends (found by Kristian Hermansen)
  • Fixed possible lockup when refreshing a login ticket
  • Disabled old style server queries by default.

Counter-Strike

  • Fixed menu exploit on join that spawned you into the server but moved you around as you were in spectator mode.
