1. Topic:
Updated openssh packages are now available for Red Hat Linux 7, 7.1, and
7.2 which close a remotely-exploitable vulnerability in sshd.
2. Relevant releases/architectures:
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386, ia64
Red Hat Linux 7.2 - i386, ia64
3. Problem description:
Joost Pol has discovered an off-by-one error in all versions of the OpenSSH
daemon (sshd) prior to version 3.1.
This issue could allow an authenticated user to cause sshd to corrupt its
heap, potentially allowing arbitrary code to be executed on the remote
server. Alternatively, a malicious SSH server could be crafted to attack a
vulnerable OpenSSH client.=20=20
Users are advised to upgrade to these errata packages containing OpenSSH
3.1, which is not vulnerable to this issue.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0083 to this issue.
4. Solution:
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
60829 - HIGH: Existing users will gain root privileges.
