Red Hat: RHSA-2017-2973-01 Moderate: nginx Security Update

Debian Security Team issues security patch for moderate vulnerability concerns impacting Ubuntu 20.04.
An update for httpd is now available for Red Hat Enterprise Linux 6

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)
* A regression was found in the Red Hat Enterprise Linux 6.9 version of httpd, causing comments in the "Allow" and "Deny" configuration lines to be parsed incorrectly. A web administrator could unintentionally allow any client to access a restricted HTTP resource. (CVE-2017-12171)
Red Hat would like to thank Hanno Böck for reporting CVE-2017-9798 and KAWAHARA Masashi for reporting CVE-2017-12171.
