Red Hat: RHSA-2017:2882-01 Moderate: httpd Remote Issue

Calendar Grey October 11, 2017
Scroller Redhat
CentOS 7 enhances its firewall settings to mitigate possible vulnerabilities in networking services, improving defense against unauthorized access.
An update for httpd is now available for Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing the updated packages, the httpd daemon will be restarted automatically.

Summary

The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server.
Security Fix(es):
* A use-after-free flaw was found in the way httpd handled invalid and previously unregistered HTTP methods specified in the Limit directive used in an .htaccess file. A remote attacker could possibly use this flaw to disclose portions of the server memory, or cause httpd child process to crash. (CVE-2017-9798)
Red Hat would like to thank Hanno Böck for reporting this issue.
