Red Hat Linux Advisory: openssl

Jul 30, 2002, 15:45 (0 Talkback[s])

---------------------------------------------------------------------
                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Updated openssl packages fix remote vulnerabilities
Advisory ID:       RHSA-2002:155-11
Issue date:        2002-07-25
Updated on:        2002-07-29
Product:           Red Hat Linux
Keywords:          OpenSSL master session key
Cross references:  
Obsoletes:         RHSA-2001:051
CVE Names:         CAN-2002-0655 CAN-2002-0656
---------------------------------------------------------------------

1. Topic:

Updated OpenSSL packages are available which fix several serious buffer
overflow vulnerabilities.

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. A security audit of the OpenSSL code sponsored by
DARPA found several buffer overflows in OpenSSL which affect versions 0.9.7
and 0.9.6d and earlier:

1. The master key supplied by a client to an SSL version 2 server could be
oversized, causing a stack-based buffer overflow. This issue is remotely
exploitable. Services that have SSLv2 disabled would not be vulnerable to
this issue. (CAN-2002-0656)

2. The SSLv3 session ID supplied to a client from a malicious server could
be oversized and overrun a buffer. This issue looks to be remotely
exploitable. (CAN-2002-0656)

3. Various buffers used for storing ASCII representations of integers were
too small on 64 bit platforms. This issue may be exploitable. (CAN-2002-0655)

A further issue was found in OpenSSL 0.9.7 that does not affect versions of
OpenSSL shipped with Red Hat Linux (CAN-2002-0657).

A large number of applications within Red Hat Linux make use the OpenSSL
library to provide SSL support.  All users are therefore advised to upgrade
to the errata OpenSSL packages, which contain patches to correct these
vulnerabilities.

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 and Ben Laurie for providing patches for
these issues.

4. Solution:

IMPORTANT:

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.
