Summary
Red Hat Security Advisory: openssl, mm, mod_ssl security update for Stronghold

Notes

Topic
A new Stronghold 3 release is available which fixes several serious buffer overflow vulnerabilities in OpenSSL, and local privilege escalation vulnerabilities in MM and mod_ssl.
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 included in Stronghold (CAN-2002-0657). The MM library provides an abstraction layer which allows related processes to easily share data. On systems where shared memory or other inter-process communication mechanisms are not available, the MM library will emulate them using temporary files. MM is used in Stronghold to providing shared memory pools to Apache modules. Versions of MM up to and including 1.1.3 open temporary files in an unsafe manner, allowing a malicious local user to cause an application which uses MM to overwrite any file to which it has write access. (CAN-2002-0658) All users are advised to upgrade to the new release which contains a patched version of MM that is not vulnerable to this issue. The mod_ssl module provides strong cryptography for the Apache Web server via the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. Versions of mod_ssl prior to 2.8.10 are subject to a single NUL byte overflow that can cause arbitrary code execution. (CAN-2002-0653) In order to exploit this vulnerability, the Apache Web server has to be configured to allow overriding of configuration settings on a per-directory basis, and untrusted local users must be able to modify a directory in which the server is configured to allow overriding. The local attacker may then become the user that Apache is running as (usually 'www' or 'nobody'). Thanks go to the OpenSSL team, Ben Laurie, and Marcus Meissner for providing patches for these issues.
