| CVE | Sev | CVSS | KEV | Affected versions | Fixed in | Published | Description |
|---|---|---|---|---|---|---|---|
| CVE-2026-0968 | Low | 3.1 | < 0.9.8-150600.11.9.1 | 0.9.8-150600.11.9.1 | Mar 26, 2026 | A flaw was found in libssh in which a malicious SFTP (SSH File Transfer Protocol) server can exploit this by sending a malformed 'longname' field within an `SSH_FXP_NAME` message during a file listing operation. This missing null check can lead to reading beyond allocated memory | |
| CVE-2026-0967 | Med | 5.5 | < 0.9.8-150600.11.9.1 | 0.9.8-150600.11.9.1 | Mar 26, 2026 | A flaw was found in libssh. A remote attacker, by controlling client configuration files or known_hosts files, could craft specific hostnames that when processed by the `match_pattern()` function can lead to inefficient regular expression backtracking. This can cause timeouts and | |
| CVE-2026-0966 | Hig | 8.2 | < 0.9.8-150600.11.9.1 | 0.9.8-150600.11.9.1 | Mar 26, 2026 | A flaw was found in libssh. The API function `ssh_get_hexa()` is vulnerable to a denial of service when processing zero-length input. This can be exploited remotely by an attacker during GSSAPI (Generic Security Service Application Program Interface) authentication if the server' | |
| CVE-2026-0965 | Low | 3.3 | < 0.9.8-150600.11.9.1 | 0.9.8-150600.11.9.1 | Mar 26, 2026 | A flaw was found in libssh where it can attempt to open arbitrary files during configuration parsing. A local attacker can exploit this by providing a malicious configuration file or when the system is misconfigured. This vulnerability could lead to a Denial of Service (DoS) by c | |
| CVE-2026-0964 | Med | 6.3 | < 0.9.8-150600.11.9.1 | 0.9.8-150600.11.9.1 | Mar 26, 2026 | A malicious SCP server can send unexpected paths that could make the client application override local files outside of working directory. This could be misused to create malicious executable or configuration files and make the user execute them under specific consequences. This | |
| CVE-2026-3731 | — | < 0.9.8-150600.11.12.1 | 0.9.8-150600.11.12.1 | Mar 8, 2026 | A weakness has been identified in libssh up to 0.11.3. The impacted element is the function sftp_extensions_get_name/sftp_extensions_get_data of the file src/sftp.c of the component SFTP Extension Name Handler. Executing a manipulation of the argument idx can lead to out-of-bound | ||
| CVE-2025-8277 | Low | 3.1 | < 0.9.8-150600.11.6.1 | 0.9.8-150600.11.6.1 | Sep 9, 2025 | A flaw was found in libssh's handling of key exchange (KEX) processes when a client repeatedly sends incorrect KEX guesses. The library fails to free memory during these rekey operations, which can gradually exhaust system memory. This issue can lead to crashes on the client side | |
| CVE-2025-4877 | Med | 4.5 | < 0.9.8-150600.11.3.1 | 0.9.8-150600.11.3.1 | Aug 20, 2025 | There's a vulnerability in the libssh package where when a libssh consumer passes in an unexpectedly large input buffer to ssh_get_fingerprint_hash() function. In such cases the bin_to_base64() function can experience an integer overflow leading to a memory under allocation, when | |
| CVE-2025-8114 | Med | 4.7 | < 0.9.8-150600.11.6.1 | 0.9.8-150600.11.6.1 | Jul 24, 2025 | A flaw was found in libssh, a library that implements the SSH protocol. When calculating the session ID during the key exchange (KEX) process, an allocation failure in cryptographic functions may lead to a NULL pointer dereference. This issue can cause the client or server to cra | |
| CVE-2025-4878 | Low | 3.6 | < 0.9.8-150600.11.3.1 | 0.9.8-150600.11.3.1 | Jul 22, 2025 | A vulnerability was found in libssh, where an uninitialized variable exists under certain conditions in the privatekey_from_file() function. This flaw can be triggered if the file specified by the filename doesn't exist and may lead to possible signing failures or heap corruption | |
| CVE-2025-5372 | Med | 5.0 | < 0.9.8-150600.11.3.1 | 0.9.8-150600.11.3.1 | Jul 4, 2025 | A flaw was found in libssh versions built with OpenSSL versions older than 3.0, specifically in the ssh_kdf() function responsible for key derivation. Due to inconsistent interpretation of return values where OpenSSL uses 0 to indicate failure and libssh uses 0 for success—the fu | |
| CVE-2025-5318 | — | < 0.9.8-150600.11.3.1 | 0.9.8-150600.11.3.1 | Jun 24, 2025 | A flaw was found in the libssh library in versions less than 0.11.2. An out-of-bounds read can be triggered in the sftp_handle function due to an incorrect comparison check that permits the function to access memory beyond the valid handle list and to return an invalid pointer, w |
