Updated openssh packages that fix a security issue and various bugs are now
This update has been rated as having low security impact by the CentOS
Security Response Team.
OpenSSH is OpenBSD's SSH (Secure SHell) protocol implementation. This
package includes the core files necessary for both the OpenSSH client and
OpenSSH stores hostnames, IP addresses, and keys in plaintext in the
known_hosts file. A local attacker that has already compromised a user's
SSH account could use this information to generate a list of additional
targets that are likely to have the same password or key. (CVE-2005-2666)
The following bugs have also been fixed in this update:
* The ssh client could abort the running connection when the server
application generated a large output at once.
* When 'X11UseLocalhost' option was set to 'no' on systems with IPv6
networking enabled, the X11 forwarding socket listened only for IPv6
* When the privilege separation was enabled in /etc/ssh/sshd_config, some
log messages in the system log were duplicated and also had timestamps from
an incorrect timezone.
All users of openssh should upgrade to these updated packages, which
contain backported patches to correct these issues.
