RHEL 5 / 6 : httpd (RHSA-2014:0920)

Synopsis :

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

Description :

Updated httpd packages that fix three security issues are now
available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
Important 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 httpd packages provide the Apache HTTP Server, a powerful,
efficient, and extensible web server.

A race condition flaw, leading to heap-based buffer overflows, was
found in the mod_status httpd module. A remote attacker able to access
a status page served by mod_status on a server using a threaded
Multi-Processing Module (MPM) could send a specially crafted request
that would cause the httpd child process to crash or, possibly, allow
the attacker to execute arbitrary code with the privileges of the
'apache' user. (CVE-2014-0226)

A denial of service flaw was found in the way httpd's mod_deflate
module handled request body decompression (configured via the
'DEFLATE' input filter). A remote attacker able to send a request
whose body would be decompressed could use this flaw to consume an
excessive amount of system memory and CPU on the target system.
(CVE-2014-0118)

A denial of service flaw was found in the way httpd's mod_cgid module
executed CGI scripts that did not read data from the standard input. A
remote attacker could submit a specially crafted request that would
cause the httpd child process to hang indefinitely. (CVE-2014-0231)

All httpd users are advised to 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.
