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

Notes

Topic
Updated versions of Stronghold 4 cross-platform are available to fix a number of vulnerabilities in OpenSSL, Apache, PHP, and Tomcat. Also included in this update are bug fixes for mod_proxy and the mod_authz_ldap package.
Details
Stronghold 4 cross platform contains a number of open source technologies such as OpenSSL, Apache, and PHP. A number of issues 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 Apache Web server does not prevent escape sequences from being written to the error log. This could allow an attacker to embed arbitrary escape sequences into the log file. 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. A source code exposure vulnerability has been found that affects Tomcat versions 4.0.0 through 4.0.5 and 4.1.0 through 4.1.12, in a variant of the issue addressed in RHSA-2002:217. Using a carefully crafted request, a remote attacker can read the source code of any deployed JSP file. In addition to the security fixes, two bug fixes have also been applied: If Apache is configured to act as a reverse proxy by specifying the backend server using a numeric IP address, the mod_proxy module will perform a redundant reverse DNS lookup on the IP address, causing a delay in request processing. A bug in mod_authz_ldap version 0.21 and earlier prevent authentication being performed by other Apache modules (such as filed-based authentication using mod_auth) when the mod_authz_ldap module is loaded. Stronghold 4 cross platform contains OpenSSL 0.9.6c, Apache 1.3.22, PHP 4.1.2, Tomcat 4.0.5, and mod_authz_ldap 0.19, and is therefore vulnerable to these issues. Users of Stronghold are advised to update to the errata versions of Stronghold 4 which contain backported security fixes and are not vulnerable to these issues.
