Synopsis: Updated openssl packages fix protocol parsing bugs
Advisory ID: RHSA-2002:160-21
Issue date: 2002-07-29
Updated on: 2002-08-05
Product: Red Hat Linux
Keywords: OpenSSL ASN.1 abstract syntax notation
Cross references:
Obsoletes: RHSA-2002:155
CVE Names: CAN-2002-0659
---------------------------------------------------------------------

1. Topic:

Updated OpenSSL packages are available for Red Hat Linux 6.2, 7, 7.1, 7.2,
and 7.3. These updates fix multiple protocol parsing bugs which may be used
in a denial of service (DoS) attack or cause SSL-enabled applications to crash.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - alpha, i386, sparc

Red Hat Linux 7.0 - alpha, i386

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, i686, ia64

Red Hat Linux 7.3 - i386, i686

3. Problem description:

OpenSSL is a commercial-grade, full-featured, and open source toolkit which
implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength general purpose
cryptography library.

Portions of the SSL protocol data stream, which include the lengths of
structures which are being transferred, may not be properly validated. This
may allow a malicious server or client to cause an affected application to
crash or enter an infinite loop, which can be used as a denial of service
(DoS) attack if the application is a server. It has not been verified if
this issue could lead to further consequences such as remote code execution.

These errata packages contain a patch to correct this vulnerability.
Please note that the original patch from the OpenSSL team had a mistake in
it which could possibly still allow buffer overflows to occur. This bug is
also fixed in these errata packages.

NOTE:

Please read the Solution section below as it contains instructions for
making sure that all SSL-enabled processes are restarted after the update
is applied.

Thanks go to the OpenSSL team for providing patches for this issue.

4. Solution:

Because both client and server applications are affected by these
vulnerabilities, we advise users to reboot their systems after installing
these updates.

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.
