This requires a scenario where the username on the command line is untrusted, and also requires a non-default configurations of % in ssh_config. | |
| CVE-2026-35385 | Hig | 7.5 | < 9.9p1-14.el10_1.alma.1 | 9.9p1-14.el10_1.alma.1 | Apr 2, 2026 | In OpenSSH before 10.3, a file downloaded by scp may be installed setuid or setgid, an outcome contrary to some users' expectations, if the download is performed as root with -O (legacy scp protocol) and without -p (preserve mode). | |

The usage of sshpkt_disconnect() on an error, which does | |
| CVE-2025-61985 | Low | 3.6 | < 9.9p1-12.el10_1.alma.1 | 9.9p1-12.el10_1.alma.1 | Oct 6, 2025 | ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a ProxyCommand is used. | |

The untrusted sources are the command line and %-sequence expansion of a configuration file | |

A machine-in-the-middle attack can be performed by a malicious machine impersonating a legit server. This issue occurs due to how OpenSSH mishandles error codes in specific conditions when verifying | |
| CVE-2024-6409 | Hig | 7.0 | < 8.7p1-38.el9_4.4 | 8.7p1-38.el9_4.4 | Jul 8, 2024 | A race condition vulnerability was discovered in how signals are handled by OpenSSH's server (sshd). If a remote attacker does not authenticate within a set time period, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions tha | |
| CVE-2024-6387 | Hig | 8.1 | < 8.7p1-38.el9_4.1 | 8.7p1-38.el9_4.1 | Jul 1, 2024 | A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time pe | |

| CVE-2023-38408 | — | < 8.7p1-30.el9_2 | 8.7p1-30.el9_2 | Jul 20, 2023 | The PKCS#11 feature in ssh-agent in OpenSSH before 9.3p2 has an insufficiently trustworthy search path, leading to remote code execution if an agent is forwarded to an attacker-controlled system. (Code in /usr/lib is not necessarily safe for loading into ssh-agent.) NOTE: this is | ||
| CVE-2023-25136 | Med | 6.5 | < 8.7p1-29.el9_2 | 8.7p1-29.el9_2 | Feb 3, 2023 | OpenSSH server (sshd) 9.1 introduced a double-free vulnerability during options.kex_algorithms handling. This is fixed in OpenSSH 9.2. The double free can be leveraged, by an unauthenticated remote attacker in the default configuration, to jump to any location in the sshd address | |
| CVE-2021-41617 | Hig | 7.0 | < 8.0p1-13.el8 | 8.0p1-13.el8 | Sep 26, 2021 | 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. Helper programs for AuthorizedKeysCommand and AuthorizedPrincipalsCommand may run with privileges | |
| CVE-2020-15778 | — | < 8.0p1-24.el8 | 8.0p1-24.el8 | Jul 24, 2020 | scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument.
