In libssh2 before 1.9.0, kex_method_diffie_hellman_group_exchange_sha256_key_exchange in kex.c has an integer overflow that could lead to an out-of-bounds read in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. This is related to an _libssh2_check_length mistake, and is different from the various issues fixed in 1.8.1, such as CVE-2019-3855.

CVE-2019-3863 [HIGH] libssh2 vulnerabilities
Title: libssh2 vulnerabilities
Summary: Several security issues were fixed in libssh2.
It was discovered that libssh2 mishandled certain input. If libssh2 were
used to connect to a malicious or compromised SSH server, a remote,
unauthenticated attacker could possibly execute arbitrary code on the client
system. (CVE-2019-3855)
It was discovered that libssh2 incorrectly handled prompt requests. A
remote attacker could possibly use this issue to execute arbitrary code.
(CVE-2019-3856)
It was discovered that libssh2 incorrectly handled SSH_MSG_CHANNEL_REQUEST
packets. A remote attacker could possibly use this issue to execute
arbitrary code, cause a denial of service, or obtain sensitive information.
