| Descripción: | Summary:
The remote host is missing an update for the 'httpd'
package(s) announced via the referenced advisory.
Vulnerability Insight:
The httpd packages contain the Apache HTTP Server (httpd), which is the
namesake project of The Apache Software Foundation.
An input sanitization flaw was found in the mod_negotiation Apache HTTP
Server module. A remote attacker able to upload or create files with
arbitrary names in a directory that has the MultiViews options enabled,
could use this flaw to conduct cross-site scripting attacks against users
visiting the site. (CVE-2008-0455, CVE-2012-2687)
It was discovered that mod_proxy_ajp, when used in configurations with
mod_proxy in load balancer mode, would mark a back-end server as failed
when request processing timed out, even when a previous AJP (Apache JServ
Protocol) CPing request was responded to by the back-end. A remote
attacker able to make a back-end use an excessive amount of time to
process a request could cause mod_proxy to not send requests to back-end
AJP servers for the retry timeout period or until all back-end servers
were marked as failed. (CVE-2012-4557)
These updated httpd packages include numerous bug fixes and enhancements.
Space precludes documenting all of these changes in this advisory. Users
are directed to the Red Hat Enterprise Linux 6.4 Technical Notes, linked
to in the References, for information on the most significant of these
changes.
All users of httpd are advised to upgrade to these updated packages, which
contain backported patches to correct these issues and add these
enhancements. After installing the updated packages, the httpd daemon will
be restarted automatically.
Affected Software/OS:
httpd on CentOS 6
Solution:
Please install the updated packages.
