RHEL 2.1 : openssl (RHSA-2002:161)

Medium Nessus Plugin ID 12316


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


Updated OpenSSL packages are available for Red Hat Linux Advanced Server. These updates fix multiple protocol parsing bugs, which may cause a denial of service (DoS) attack or cause SSL-enabled applications to crash.

[Updated 06 Jan 2003] Added fixed packages for the ia64 architecture.

[Updated 06 Feb 2003] Added fixed packages for Advanced Workstation 2.1

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.


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 these issues.


Update the affected packages.
