CVSS 3.1
8.1 highCVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:HCVE-2019-13115
High (8.1). EPSS 12% chance of exploitation in the next 30 days.
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.
