Summary
Red Hat Security Advisory: apache, openssl, php security update for Stronghold

Notes

Topic
Updated versions of Stronghold 3.0 are available to fix a number of vulnerabilities in OpenSSL, Apache, and PHP.
Details
Stronghold 3.0 contains a number of open source technologies such as OpenSSL, Apache, and PHP. The following paragraphs describe a number of issues that have been found in versions of these projects. In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites in SSL and TLS. An active attacker may be able to use timing observations to distinguish between two different error cases: cipher padding errors and MAC verification errors. Over multiple connections this can leak sufficient information to be able to retrieve the plain text of a common, fixed block. In order for an attack to be successful an attacker must be able to act as a man-in-the-middle to intercept and modify multiple connections which all involve a common fixed plain text block (such as a password), and have good network conditions that allow small changes in timing to be reliably observed. The SSL timing attack announced recently by David Brumly and Dan Boneh is not fixed by this erratum; this new issue will be addressed by a future erratum release. The Apache Web server does not prevent escape sequences from being written to log files. This could allow an attacker to embed arbitrary escape sequences into log files. A recent paper by HD Moore highlighted several issues where common terminal emulator software (such as xterm) can be remotely abused or exploited by displaying arbitrary escape sequences. The MySQL client library (libmysqlclient) used in the PHP MySQL extension in PHP versions earlier than 4.3.0 does not properly verify length fields for certain responses in the read_rows or read_one_row routines, which allows a malicious server to cause a denial of service and possibly execute arbitrary code. Stronghold 3.0 contains OpenSSL 0.9.6b, Apache 1.3.22, and PHP 4.1.2 and is, therefore, vulnerable to these issues. Users of Stronghold are advised to update to the errata versions of Stronghold 3.0 which contain backported security fixes and are not vulnerable to these issues.
