RedHat: RHSA-2017-2972:01 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)
* 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.
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.
