Fedora Update Notification
FEDORA-2018-0a95bff197
2018-04-05 23:56:01.161334
——————————————————————————–

Name : mod_http2
Product : Fedora 27
Version : 1.10.16
Release : 1.fc27
URL : https://icing.github.io/mod_h2/
Summary : module implementing HTTP/2 for Apache 2
Description :
The mod_h2 Apache httpd module implements the HTTP2 protocol (h2+h2c) on
top of libnghttp2 for httpd 2.4 servers.

Update Information:

This update includes the latest upstream release of mod_http2, version 1.10.16.
This includes a security fix (CVE-2018-1302): When an HTTP/2 stream was
destroyed after being handled, mod_http2 could have written a NULL pointer
potentially to an already freed memory. The memory pools maintained by the
server make this vulnerabilty hard to trigger in usual configurations, the
reporter and the team could not reproduce it outside debug builds, so it is
classified as low risk.
