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

Notes

Topic
Updated versions of cross-platform Stronghold that fix security issues in mod_ssl, PHP, and the Apache HTTP Server are now available.
Details
Stronghold 4 contains a number of open source technologies, including PHP, mod_ssl and the Apache HTTP Server. Stefan Esser discovered a flaw when the memory_limit configuration setting was enabled in PHP 4 versions prior to 4.3.8. If a remote attacker could force the PHP interpreter to allocate more memory than the memory_limit setting before script execution begins, then the attacker may be able to supply the contents of a PHP hash table remotely. This hash table could then be used to execute arbitrary code as the 'apache' user. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0594 to this issue. It may be possible to exploit this issue if using a non-default PHP configuration with the "register_defaults" setting is changed to "On". Red Hat does not believe that this flaw is exploitable in the default configuration of Stronghold 4. Stefan Esser discovered a flaw in the strip_tags function in versions of PHP prior to 4.3.8. The strip_tags function is commonly used by PHP scripts to prevent cross-site scripting attacks by removing HTML tags from user-supplied form data. By embedding NUL bytes into form data, HTML tags can in some cases be passed intact through the strip_tags function, which may allow a cross-site scripting attack. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0595 to this issue. A stack buffer overflow was discovered in mod_ssl which can be triggered if using the FakeBasicAuth option. If mod_ssl is sent a client certificate with a subject DN field longer than 6000 characters, a stack overflow can occur if FakeBasicAuth has been enabled. In order to exploit this issue, the carefully crafted malicious certificate would have to be signed by a Certificate Authority which mod_ssl is configured to trust. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0488 to this issue. A format string issue was discovered in mod_ssl which can be triggered if mod_ssl is configured to allow a client to proxy to remote SSL sites. If mod_ssl is forced to connect to a remote SSL server using a carefully crafted hostname, an attacker may be able to crash an Apache child process. This issue is not known to allow arbitrary execution of code. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0700 to this issue. A denial of service issue was discovered which affects versions of the Apache HTTP Server prior to 1.3.30. On some platforms, when Apache is configured with multiple listening sockets, a short-lived connection to one socket may temporarily block new connections to other sockets. This issue does not affect Stronghold if running on Linux, FreeBSD or HP-UX platforms. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0174 to this issue. Users of Stronghold 4 cross-platform are advised to update to these errata versions, which contain backported security fixes and are not vulnerable to these issues.
