| Descripción: | Description:
The remote host is missing updates announced in
advisory RHSA-2005:582.
The Apache HTTP Server is a powerful, full-featured, efficient, and
freely-available Web server.
Watchfire reported a flaw that occured when using the Apache server as an
HTTP proxy. A remote attacker could send an HTTP request with both a
Transfer-Encoding: chunked header and a Content-Length header. This
caused Apache to incorrectly handle and forward the body of the request in
a way that the receiving server processes it as a separate HTTP request.
This could allow the bypass of Web application firewall protection or lead
to cross-site scripting (XSS) attacks. The Common Vulnerabilities and
Exposures project (cve.mitre.org) assigned the name CVE-2005-2088 to this
issue.
Marc Stern reported an off-by-one overflow in the mod_ssl CRL verification
callback. In order to exploit this issue the Apache server would need to
be configured to use a malicious certificate revocation list (CRL). The
Common Vulnerabilities and Exposures project (cve.mitre.org) assigned the
name CVE-2005-1268 to this issue.
Users of Apache httpd should update to these errata packages that contain
backported patches to correct these issues.
