|
| VCID-g1vx-bcxw-mqfg | A certain Debian patch for OpenSSH before 4.3p2-9etch3 on etch; before 4.6p1-1 on sid and lenny; and on other distributions such as SUSE uses functions that are not async-signal-safe in the signal handler for login timeouts, which allows remote attackers to cause a denial of service (connection slot exhaustion) via multiple login attempts.

CVE-2016-3115
|
| VCID-hmyj-ztb3-rbhz | FreeBSD 9.1, 9.2, and 10.0, when compiling OpenSSH with Kerberos support, uses incorrect library ordering when linking sshd, which causes symbols to be resolved incorrectly and allows remote attackers to cause a denial of service (sshd deadlock and prevention of new connections) by ending multiple connections before authentication is completed. |

CVE-2010-4478
|
| VCID-jzk9-kyvp-5qdz | OpenSSH 4.0, and other versions before 4.2, does not properly handle dynamic port forwarding ("-D" option) when a listen address is not provided, which may cause OpenSSH to enable the GatewayPorts functionality. |
CVE-2005-2797
|
| VCID-jzn6-bzzf-nugp | Improper Validation of Integrity Check Value 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 phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms.
