-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: httpd security update Advisory ID: RHSA-2017:2972-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2972 Issue date: 2017-10-19 CVE Names: CVE-2017-12171 CVE-2017-9798 ===================================================================== 1. Summary: An update for httpd is now available for Red Hat Enterprise Linux 6. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - noarch, x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 3. Description: 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 BAPck for reporting CVE-2017-9798 and KAWAHARA Masashi for reporting CVE-2017-12171. 4. 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. 5. Bugs fixed (https://bugzilla.redhat.com/): 1490344 - CVE-2017-9798 httpd: Use-after-free by limiting unregistered HTTP method (Optionsbleed) 1493056 - CVE-2017-12171 httpd: # character matches all IPs 6.
