Details

In libssh2 before 1.9.0, kexmethoddiffiehellmangroupexchangesha256keyexchange 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 libssh2check_length mistake, and is different from the various issues fixed in 1.8.1, such as CVE-2019-3855.
