Red Hat Inc. Information for VU#369347

OpenSSH vulnerabilities in challenge response handling



Vendor Statement

Red Hat Linux versions 7, 7.1, 7.2 and 7.3 as well as Red Hat Linux Advanced Server version 2.1 ship with OpenSSH. The Red Hat Linux OpenSSH packages were not compiled with either BSD_AUTH or SKEY enabled, therefore in order to be vulnerable to this issue a user would need to have enabled the configuration option "PAMAuthenticationViaKbdInt" in their sshd configuration file (the default is disabled).

We are continuing to investigate this vulnerability and will release updated packages where appropriate.
