New nghttp2 packages are available for Slackware 15.0 and -current to
fix a security issue.

Here are the details from the Slackware 15.0 ChangeLog:

patches/packages/nghttp2-1.61.0-i586-1_slack15.0.txz: Upgraded.
This update fixes security issues:
nghttp2 library keeps reading the unbounded number of HTTP/2 CONTINUATION
frames even after a stream is reset to keep HPACK context in sync. This
causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates
this vulnerability by limiting the number of CONTINUATION frames it can
accept after a HEADERS frame.
For more information, see:

(* Security fix *)
