etcd: etcd: Denial of Service via unbounded TLS handshake goroutines
A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the tlsListener.acceptLoop to spawn an unbounded number of goroutines, which consume...
PT-2026-64382
Name of the Vulnerable Software and Affected Versions libssh2 versions prior to 1.11.1 Description A pre-authentication heap buffer overflow occurs during Encrypt-then-MAC ETM cipher negotiation. A malicious SSH server can corrupt heap metadata in a connecting client by sending a packet where the...
