io.netty/netty-codec-http: Netty: Denial of Service via unbounded queue growth during HTTP request pipelining
A flaw was found in Netty. This vulnerability allows a remote, unauthenticated attacker to cause a Denial of Service DoS by sending numerous pipelined HTTP/1.1 requests over a single connection while withholding reads. Netty's HTTP server codec stores unanswered requests in an internal queue...
io.netty/netty-codec-http: Netty: Unbounded Per-Connection Queue Growth in WebSocketServerExtensionHandler Leads to Denial of Service
A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive...
Astra Linux – Vulnerability in exim4
Before version 4.97.1, Exim allowed SMTP smuggling in certain pipeline/chunking configurations. Remote attackers could use a known exploitation technique to inject e-mail messages with a spoofed MAIL FROM address, thereby bypassing an SPF protection mechanism. This issue arises because Exim...
