Summary
Red Hat Security Advisory: : Updated Apache and mod_ssl packages fix security vulnerabilities

Notes

Topic
Updated Apache and mod_ssl packages that fix several minor security issues are now available for Red Hat Linux 7.1, 7.2, and 7.3.
Details
The Apache HTTP server is a powerful, full-featured, efficient, and freely-available Web server. Ben Laurie found a bug in the optional renegotiation code in mod_ssl which can cause cipher suite restrictions to be ignored. This is triggered if optional renegotiation is used (SSLOptions +OptRenegotiate) along with verification of client certificates and a change to the cipher suite over the renegotiation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0192 to this issue. Apache does not filter terminal escape sequences from its error logs, which could make it easier for attackers to insert those sequences into terminal emulators containing vulnerabilities related to escape sequences. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-0020 to this issue. It is possible to get Apache 1.3 to get into an infinite loop handling internal redirects and nested subrequests. A patch for this issue adds a new LimitInternalRecursion directive. All users of the Apache HTTP Web Server are advised to upgrade to the applicable errata packages, which contain back-ported fixes correcting these issues. After the errata packages are installed, restart the Web service by running the following command: /sbin/service httpd restart
