From 8909ff0e3cd07d1b042d1be1c8b8828dbf6c9a83 Mon Sep 17 00:00:00 2001 From: Colin Watson Date: Sun, 9 Feb 2014 16:09:50 +0000 Subject: Reject vulnerable keys to mitigate Debian OpenSSL flaw In 2008, Debian (and derived distributions such as Ubuntu) shipped an OpenSSL package with a flawed random number generator, causing OpenSSH to generate only a very limited set of keys which were subject to private half precomputation. To mitigate this, this patch checks key authentications against a blacklist of known-vulnerable keys, and adds a new ssh-vulnkey program which can be used to explicitly check keys against that blacklist. See CVE-2008-0166.
