nghttp2: Denial of service

nghttp2: Denial of service Nghttp2 is vulnerable to a Denial of Service attack. nghttp2 2016-12-05 2016-12-05 574780 remote 1.7.1 1.7.1

Nghttp2 is an implementation of HTTP/2 and its header compression algorithm HPACK in C.

Nghttpd, nghttp, and libnghttp2_asio applications do not limit the memory usage for the incoming HTTP header field. If a peer sends a specially crafted HTTP/2 HEADERS frame and CONTINUATION frame, they will crash with an out of memory error.

A remote attacker could possibly cause a Denial of Service condition.

There is no known workaround at this time.

All nghttp2 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-libs/nghttp2-1.7.1"
