RHEL 3 : openssh (RHSA-2006:0298)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated openssh packages that fix bugs in sshd are now available for
Red Hat Enterprise Linux 3.

This update has been rated as having low security impact by the Red
Hat 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 server.

An arbitrary command execution flaw was discovered in the way scp
copies files locally. It is possible for a local attacker to create a
file with a carefully crafted name that could execute arbitrary
commands as the user running scp to copy files locally.
(CVE-2006-0225)

The SSH daemon, when restricting host access by numeric IP addresses
and with VerifyReverseMapping disabled, allows remote attackers to
bypass 'from=' and 'user@host' address restrictions by connecting to a
host from a system whose reverse DNS hostname contains the numeric IP
address. (CVE-2003-0386)

The following issues have also been fixed in this update :

* If the sshd service was stopped using the sshd init script while the
main sshd daemon was not running, the init script would kill other
sshd processes, such as the running sessions. For example, this could
happen when the 'service sshd stop' command was issued twice.

* When privilege separation was enabled, the last login message was
printed only for the root user.

* The sshd daemon was sending messages to the system log from a signal
handler when debug logging was enabled. This could cause a deadlock of
the user's connection.

All users of openssh should upgrade to these updated packages, which
resolve these issues.
