Summary

In OpenSSH versions prior to 7.4, there's a significant vulnerability due to improper handling of buffer contents during reallocation. This flaw allows local users, with access to a privilege-separated child process, to potentially extract sensitive private-key information. The design oversight in the authfile.c file means that the security of private keys can be compromised, exposing critical user data to unauthorized access.
