Debian Security Advisory DSA-1576-2 security@debian.org
http://www.debian.org/security/ Noah Meyerhans
May 16, 2008 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : openssh
Vulnerability : predictable random number generator
Problem type : remote
Debian-specific: yes
CVE Id(s) : CVE-2008-0166

Matt Zimmerman discovered that entries in ~/.ssh/authorized_keys with
options (such as "no-port-forwarding" or forced commands) were ignored by
the new ssh-vulnkey tool introduced in openssh 1:4.3p2-9etch1 (see DSA
1576-1). This could cause some compromised keys not to be listed in
ssh-vulnkey's output.

This update also adds more information to ssh-vulnkey's manual page.

For the stable distribution (etch), this problem has been fixed in version
1:4.3p2-9etch2

We recommend that you upgrade your openssh (1:4.3p2-9etch2) package.

Upgrade instructions
- --------------------

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update

You may use an automated update by adding the resources from the
footer to the proper configuration.
