Summary
Red Hat Security Advisory: : Updated openssl packages fix remote vulnerabilities

Notes

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