nghttp2: nghttp2: HTTP Request/Response Smuggling and Response-Queue Poisoning via ambiguous HTTP/1.1 Upgrade requests

A flaw in nghttp2's nghttpx proxy allows a remote attacker to perform HTTP request smuggling and cross-client response-queue poisoning. This occurs because the proxy ambiguously forwards HTTP/1.1 Upgrade requests that contain a Content-Length header to reusable keep-alive backend connections...

kernel: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackh323 module. This vulnerability occurs in the DecodeQ931 function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value...
