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.
