2023-02-02 21:04:55 The kex_agree_methods function in libssh2 before 1.5.0 allows remote servers to cause a denial of service (crash) or have other unspecified impact via crafted length values in an SSH_MSG_KEXINIT packet. A flaw was found in the way the kex_agree_methods() function of libssh2 performed a key exchange when negotiating a new SSH session. A man-in-the-middle attacker could use a crafted SSH_MSG_KEXINIT packet to crash a connecting libssh2 client. Description updated
