GLSA-201612-13 : nghttp2: Denial of Service
Medium Nessus Plugin ID 95528
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201612-13 (nghttp2: Denial of Service)
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.
SolutionAll nghttp2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-libs/nghttp2-1.7.1'
