Amazon Linux AMI Security Advisory: ALAS-2017-896
Advisory Release Date: 2017-09-18 18:30 Pacific
Severity: Important
References: CVE-2017-9798 

Issue Overview:

Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration.(CVE-2017-9798 )
