CVE-2026-59842 · Libssh: libssh: information disclosure via short gssapi curve25519 public key
This page contains facts from public vulnerability sources. Check the original advisory before updating.
A flaw was found in libssh. During server-side GSSAPI key exchange, a client-supplied Curve25519 public key shorter than the expected length is copied without proper length validation, leading to an out-of-bounds heap read. This could allow a remote unauthenticated attacker to disclose small amounts of server memory.
