"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
these issues.

After the errata packages are installed, restart the Web service by
running the following command :

/sbin/service httpd restart"
