The remote Red Hat host is missing one or more security updates.
Updated OpenSSL packages are available which fix several serious
buffer overflow vulnerabilities.
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. (CVE-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. (CVE-2002-0656)
3. Various buffers used for storing ASCII representations of integers
were too small on 64 bit platforms. This issue may be exploitable.
A further issue was found in OpenSSL 0.9.7 that does not affect
versions of OpenSSL shipped with Red Hat Linux (CVE-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.
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.
