Synopsis

Description

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.
Impact :

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

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