| DATE | CVE | VULNERABILITY TITLE | RISK |
|---|---|---|---|
| 2024-07-01 | CVE-2024-6387 | Race Condition vulnerability in multiple products A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). | 8.1 |
| 2023-12-24 | CVE-2023-51767 | OpenSSH through 9.6, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. | 7.0 |
| 2021-09-26 | CVE-2021-41617 | sshd in OpenSSH 6.2 through 8.x before 8.8, when certain non-default configurations are used, allows privilege escalation because supplemental groups are not initialized as expected. | 7.0 |
| 2021-03-05 | CVE-2021-28041 | Double Free vulnerability in multiple products ssh-agent in OpenSSH before 8.5 has a double free that may be relevant in a few less-common scenarios, such as unconstrained agent-socket access on a legacy operating system, or the forwarding of an agent to an attacker-controlled host. | 7.1 |
| 2020-07-24 | CVE-2020-15778 | OS Command Injection vulnerability in multiple products scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. | 7.8 |
| 2020-06-01 | CVE-2020-12062 | Improper Input Validation vulnerability in Openbsd Openssh 8.2 The scp client in OpenSSH 8.2 incorrectly sends duplicate responses to the server upon a utimes system call failure, which allows a malicious unprivileged user on the remote server to overwrite arbitrary files in the client's download directory by creating a crafted subdirectory anywhere on the remote server. | 7.5 |
| 2019-10-09 | CVE-2019-16905 | Integer Overflow or Wraparound vulnerability in multiple products OpenSSH 7.7 through 7.9 and 8.x before 8.1, when compiled with an experimental key type, has a pre-authentication integer overflow if a client or server is configured to use a crafted XMSS key. | 7.8 |
| 2018-01-21 | CVE-2016-10708 | NULL Pointer Dereference vulnerability in multiple products sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c. | 7.5 |
| 2017-01-05 | CVE-2016-10012 | Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in Openbsd Openssh The shared memory manager (associated with pre-authentication compression) in sshd in OpenSSH before 7.4 does not ensure that a bounds check is enforced by all compilers, which might allows local users to gain privileges by leveraging access to a sandboxed privilege-separation process, related to the m_zback and m_zlib data structures. | 7.8 |
| 2017-01-05 | CVE-2016-10010 | Permissions, Privileges, and Access Controls vulnerability in Openbsd Openssh sshd in OpenSSH before 7.4, when privilege separation is not used, creates forwarded Unix-domain sockets as root, which might allow local users to gain privileges via unspecified vectors, related to serverloop.c. | 7.0 |
