| CVE | Sev | CVSS | KEV | Affected versions | Fixed in | Published | Description |
|---|---|---|---|---|---|---|---|
| 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. | |
| CVE-2025-61984 | 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 control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file | |
| CVE-2025-32728 | Med | 4.3 | < 9.9p1-11.el10.alma.1 | 9.9p1-11.el10.alma.1 | Apr 10, 2025 | In sshd in OpenSSH before 10.0, the DisableForwarding directive does not adhere to the documentation stating that it disables X11 and agent forwarding. | |
| CVE-2025-26465 | Med | 6.8 | < 8.0p1-26.el8_10 | 8.0p1-26.el8_10 | Feb 18, 2025 | A vulnerability was found in OpenSSH when the VerifyHostKeyDNS option is enabled. 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-2023-51385 | Med | 6.5 | < 8.0p1-19.el8_9.2 | 8.0p1-19.el8_9.2 | Dec 18, 2023 | In ssh in OpenSSH before 9.6, OS command injection might occur if a user name or host name has shell metacharacters, and this name is referenced by an expansion token in certain situations. For example, an untrusted Git repository can have a submodule with shell metacharacters in | |
| CVE-2023-48795 | Med | 5.9 | < 8.0p1-19.el8_9.2 | 8.0p1-19.el8_9.2 | Dec 18, 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 | |
| CVE-2023-38408 | Cri | 9.8 | < 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 | Hig | 7.4 | < 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. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that |
