CVE-2026-11404

Cesanta Mongoose before 7.22 contains an out-of-bounds read in the built-in TLS server function mgtlsserverrecvhello, which uses an attacker-controlled sessionidlen byte from a TLS ClientHello as a buffer index without validating it against the length of received data. A remote, unauthenticated...

netty-codec-haproxy: Netty HAProxy PROXY protocol v2 codec: Denial of Service via memory leak from crafted PROXY protocol headers

A flaw was found in the Netty HAProxy PROXY protocol v2 codec. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy PROXY protocol v2 header with nested PP2TYPESSL type-length-value TLV records. This can lead to a memory leak, causing the underlying cumulation...
