CentOS Update for httpd CESA-2010:0168 centos5 i386

CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P

Summary:
The remote host is missing an update for the 'httpd' Linux Distribution Package(s) announced via the referenced advisory.

Affected Versions:
httpd on CentOS 5

Technical Details:
The Apache HTTP Server is a popular web server. It was discovered that mod_proxy_ajp incorrectly returned an 'Internal Server Error' response when processing certain malformed requests, which caused the back-end server to be marked as failed in configurations where mod_proxy is used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period (60 seconds by default) by sending specially-crafted requests. (CVE-2010-0408) A use-after-free flaw was discovered in the way the Apache HTTP Server handled request headers in subrequests. In configurations where subrequests are used, a multithreaded MPM (Multi-Processing Module) could possibly leak information from other requests in request replies. (CVE-2010-0434) This update also adds the following enhancement: * with the updated openssl Linux Distribution Packages from RHSA-2010:0162 installed, mod_ssl will refuse to renegotiate a TLS/SSL connection with an unpatched client that does not support RFC 5746. This update adds the 'SSLInsecureRenegotiation' configuration directive. If this directive is enabled, mod_ssl will renegotiate insecurely with unpatched clients. (BZ#567980) Refer to the linked Red Hat Knowledgebase article for more details about the changed mod_ssl behavior. All httpd users should upgrade to these updated Linux Distribution Packages, which contain backported patches to correct these issues and add this enhancement. After installing the updated Linux Distribution Packages, the httpd daemon must be restarted for the update to take effect.

Recommendations:
Please install the updated Linux Distribution Packages.

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
