We've released a mandatory update to Counter-Strike: Source. The notes for the update are below.
Counter-Strike: Source- Fixed a problem that allowed spoofed IP addresses to make connections to the game server
- Added ConVars sv_rcon_maxpacketsize and sv_rcon_maxpacketbans to allow server admins to control the maximum RCON packet size and whether or not users get banned for exceeding that limit. The defaults reflect the existing behavior.
- Fixed not being able to import custom spray images on Macs
- Fixed Macs cancelling http map downloads that take longer than 30 seconds
- Updated the HTML renderer for displaying server MOTD
