Valve has released a new update for the original Half-Life. The update focuses on fixing several crashes and security issues that have been reported over the past few months.
The new update fixes two crashes that occur when entering malformed strings into the game's developer console and two security holes that allowed specially crafted and malformed map and save game files to write data to the game's data folder without permission.
The update is likely released because Valve doesn't want the game to be exploited for malicious uses. If left unpatched, specially crafted malware could have potentially targeted those who still play the game regularly.
