Fedora Update Notification
FEDORA-2018-63de5f3f6b

Name : mod_http2
Product : Fedora 26
Version : 1.10.18
Release : 1.fc26
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 release includes the latest stable upstream release of mod_http2. The
changes since the last update are: * fixes a race condition where aborting
streams triggers an unnecessary timeout. * accurate reporting of h2 data
input/output per request via mod_logio. Fixes an issue where output sizes where
counted n-times on reused slave connections. See [issue
#158](https://github.com/icing/mod_h2/issues/158). * normalized connection
prefix logging when trace2 is enabled for direct h2 connection detection.
----
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.
