If you have detected that your system has already been compromised, following CERT's Network Security recovery document will assist with recommended steps for system recovery.
Vulnerability Assessment Details
Check for the version of the apache packages
Detailed Explanation for this Vulnerability Assessment
Updated Apache and mod_ssl packages that fix several minor security issues
are now available for Red Hat Enterprise Linux.
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 CVE-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 CVE-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
After the errata packages are installed, restart the Web service by running
the following command:
/sbin/service httpd restart
