CentOS 6 : httpd (CESA-2017:2972) (Optionsbleed)
Medium Nessus Plugin ID 104053
SynopsisThe remote CentOS host is missing one or more security updates.
DescriptionAn 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.
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.
Red Hat would like to thank Hanno Bock for reporting CVE-2017-9798 and KAWAHARA Masashi for reporting CVE-2017-12171.
SolutionUpdate the affected httpd packages.
