Your system information
Due to the fact that the client is 32-bit, it is very easy to exploit many "Integer Overflow" attacks (CWE-190 MITRE).
The Steam Client is too large a project, it is functionally complex, and since 2014 this type of vulnerability can be exploited, it is impossible to cover and fix all types for guard from IO until there is a 64-bit port.
