mod_proxy_http.c in mod_proxy_http in the Apache HTTP Server 2.2.9 through 2.2.15, 2.3.4-alpha, and 2.3.5-alpha on Windows, NetWare, and OS/2, in certain configurations involving proxy worker pools, does not properly detect timeouts, which allows remote attackers to obtain a potentially sensitive response intended for a different client in opportunistic circumstances via a normal HTTP request.

mod_proxy in httpd in Apache HTTP Server 2.2.9, when running on Unix, does not close the backend connection if a timeout occurs when reading a response from a persistent connection, which allows remote attackers to obtain a potentially sensitive response intended for a different client in opportunistic circumstances via a normal HTTP request. NOTE:
this is the same issue as CVE-2010-2068, but for a different OS and set of affected versions. (CVE-2010-2791)

According to its banner, the version of Oracle HTTP Server installed on the remote host is potentially affected by multiple vulnerabilities. 

Note that Nessus did not verify if patches or workarounds have been applied.

Updated httpd packages that fix two security issues and multiple bugs are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The Apache HTTP Server is a popular web server.

A flaw was discovered in the way the mod_proxy module of the Apache HTTP Server handled the timeouts of requests forwarded by a reverse proxy to the back-end server. If the proxy was configured to reuse existing back-end connections, it could return a response intended for another user under certain timeout conditions, possibly leading to information disclosure. (CVE-2010-2791)

A flaw was found in the way the mod_dav module of the Apache HTTP Server handled certain requests. If a remote attacker were to send a carefully crafted request to the server, it could cause the httpd child process to crash. (CVE-2010-1452)

This update also fixes the following bugs :

* numerous issues in the INFLATE filter provided by mod_deflate.
'Inflate error -5 on flush' errors may have been logged. This update upgrades mod_deflate to the newer upstream version from Apache HTTP Server 2.2.15. (BZ#625435)

* the response would be corrupted if mod_filter applied the DEFLATE filter to a resource requiring a subrequest with an internal redirect.
(BZ#625451)

* the OID() function used in the mod_ssl 'SSLRequire' directive did not correctly evaluate extensions of an unknown type. (BZ#625452)

All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect.

According to the web server's banner, the version of HP System Management Homepage (SMH) hosted on the remote host is earlier than 7.0.  As such, it is reportedly affected by the following vulnerabilities :

 - An unspecified input validation error exists and can    allow cross-site request forgery attacks. (CVE-2011-3846)

 - Unspecified errors can allow attackers to carry out    denial of service attacks via unspecified vectors.
   (CVE-2012-0135, CVE-2012-1993)
