2014-02-09Reject vulnerable keys to mitigate Debian OpenSSL flawColin Watson
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. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1469 Last-Update: 2013-09-14 Patch-Name: ssh-vulnkey.patch
