CVE-2016-6581

CVE-2016-6581 affects HTTP/2 implementations built with the Python HPACK library in versions 1.0.0 through 2.2.0. The vulnerability stems from an HPACK Bomb scenario: an attacker inserts a header field the size of the dynamic HPACK table into the table, then sends a header block that repeatedly e...

CVE-2016-6581

A HTTP/2 implementation built using any version of the Python HPACK library between v1.0.0 and v2.2.0 could be targeted for a denial of service attack, specifically a so-called "HPACK Bomb" attack. This attack occurs when an attacker inserts a header field that is exactly the size of the HPACK...

4 Flaws hit HTTP/2 Protocol that could allow Hackers to Disrupt Servers

If you think that the HTTP/2 protocol is more secure than the standard HTTP Hypertext Transfer Protocol, then you might be wrong, as it took researchers just four months to discover four flaws in the HTTP/2 protocol. HTTP/2 was launched properly just in May last year after Google bundled its SPDY...

nghttp2: denial of service

HTTP/2 uses HPACK to compress header fields. The basic idea is that HTTP header field is stored in the receiver with the numeric index number. The memory used by this storage is tightly constrained, and it is 4KiB by default. When sender sends the same header field, it just sends the correspondin...
