https://notcve.org/view.php?id=CVE-2023-48795
18 Dec 2023 — The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phas... • https://packetstorm.news/files/id/176280 • CWE-222: Truncation of Security-relevant Information CWE-354: Improper Validation of Integrity Check Value •

https://notcve.org/view.php?id=CVE-2020-22218
22 Aug 2023 — An issue was discovered in function _libssh2_packet_add in libssh2 1.10.0 allows attackers to access out of bounds memory. A flaw was found in the libssh2 library. An out-of-bounds access issue can occur due to an improper initialization of a variable, resulting in a crash in the application linked to the library. It was discovered that libssh2 incorrectly handled memory access. An attacker could possibly use this issue to cause a crash. • https://github.com/libssh2/libssh2/pull/476 • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

21 Oct 2019 — In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted 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.

16 Jul 2019 — 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 ... • https://packetstorm.news/files/id/172834 • CWE-125: Out-of-bounds Read CWE-190: Integer Overflow or Wraparound •
