RedHat: RHSA-2017-2882:01 Moderate: httpd security update
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.
Summary
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.
