Janine, I believe that
OpenSSH
uses the
OpenSSL
libraries, but
not vice-versa. I am not at all certain, but
the Debian package dependencies in the links above appear to show
this.
So perhaps it's that some folks are upgrading OpenSSL at the same time
they upgraded OpenSSH, and then breaking OpenSSL thread-safety due to
silly header file and build changes in OpenSSL?
