Updated openssh packages available
| Advisory: | RHSA-2001:033-04 |
|---|---|
| Type: | Security Advisory |
| Severity: | N/A |
| Issued on: | 2001-03-23 |
| Last updated on: | 2001-03-27 |
| Affected Products: | Red Hat Linux 7.0 |
| CVEs (cve.mitre.org): |
CVE-2001-0572 |
Details
Updated openssh packages are now available for Red Hat Linux 7. These
packages reduce the amount of information a passive attacker can deduce
from observing an encrypted session.
Weaknesses in the SSH protocols can be used by a passive attacker to deduce
information about passwords entered over an encrypted connection. This
information can be used to reduce the number of possible solutions which
need to be tested to perform a brute-force attack. This reduces the amount
of time and resources required to mount such an attack successfully.
OpenSSH 2.5.1 and 2.5.2 include modifications which, while not completely
resolving this problem, reduce the risks by changing certain server
behaviors to make passive analysis more difficult.
Solution
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 directly *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.
