Título:	RedHat Security Advisory RHSA-2002:161
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2002:161. 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. Thanks go to the OpenSSL team for providing patches for these issues. Solution: Please note that this update is available via Red Hat Network. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date Because both client and server applications are affected by these vulnerabilities, we advise users to reboot their systems after installing these updates. http://rhn.redhat.com/errata/RHSA-2002-161.html Risk factor : Medium CVSS Score: 5.0
