NVD Description

Note: Versions mentioned in the description apply only to the upstream h2o package and not the h2o package as distributed by Debian.

lib/http2/connection.c in H2O before 1.7.3 and 2.x before 2.0.0-beta5 mishandles HTTP/2 disconnection, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly execute arbitrary code via a crafted packet.
