Summary: An update for rh-nginx110-nginx is now available for Red Hat Software Collections. Red Hat Product Security has rated this update as having a security impact of Low. 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 Software Collections for Red Hat Enterprise Linux Server (v. 6) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 7) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.7) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 7.3) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 6) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 7) - x86_64 3. Description: Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and IMAP protocols, with a strong focus on high concurrency, performance and low memory usage. Security Fix(es): * A flaw within the processing of ranged HTTP requests has been discovered in the range filter module of nginx. A remote attacker could possibly exploit this flaw to disclose parts of the cache file header, or, if used in combination with third party modules, disclose potentially sensitive memory by sending specially crafted HTTP requests. (CVE-2017-7529) Red Hat would like to thank the Nginx project for reporting this issue. 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 5.
