Security Fix(es) :

  • mod_http2: HTTP/2: 0-length headers leads to denial of service (CVE-2019-9516)

  • mod_http2: HTTP/2: request for large response leads to denial of service (CVE-2019-9517)

Bug Fix(es) :

  • nghttp2: Rebase to 1.39.2

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
