Valve Software valvesoftware SteamOS Beta

Valve Steam 3.42.16.13 uses weak permissions for the files in the Steam program directory, which allows local users to modify the files and possibly gain privileges as demonstrated by a Trojan horse Steam.exe file.

Valve Bug Reporter in the valve-bugreporter package 2.10+bsos1 in Valve SteamOS Beta stores cleartext credentials in a .valve-bugreporter.cfg file upon a Remember Credentials action, which allows local users to obtain sensitive information by reading this file.
