New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated httpd packages that fix multiple security issues are now available for Red Hat Enterprise Linux 6.

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.

It was discovered that the fix for CVE-2011-3368 (released via RHSA-2011:1391) did not completely address the problem. An attacker could bypass the fix and make a reverse proxy connect to an arbitrary server not directly accessible to the attacker by sending an HTTP version 0.9 request, or by using a specially crafted URI.
(CVE-2011-3639, CVE-2011-4317)

The httpd server included the full HTTP header line in the default error page generated when receiving an excessively long or malformed header. Malicious JavaScript running in the server's domain context could use this flaw to gain access to httpOnly cookies.
(CVE-2012-0053)

An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way httpd performed substitutions in regular expressions.
An attacker able to set certain httpd settings, such as a user permitted to override the httpd configuration for a specific directory using a '.htaccess' file, could use this flaw to crash the httpd child process or, possibly, execute arbitrary code with the privileges of the 'apache' user. (CVE-2011-3607)

A flaw was found in the way httpd handled child process status information. A malicious program running with httpd child process privileges (such as a PHP or CGI script) could use this flaw to cause the parent httpd process to crash during httpd service shutdown.
(CVE-2012-0031)

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 will be restarted automatically.

Solution

Update the affected packages.
