CVE-2023-2283 (GCVE-0-2023-2283)

Vulnerability from – Published: 2023-05-26 00:00 – Updated: 2025-11-03 20:35
VLAI?
Summary
A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the`pki_verify_data_signature` function in memory allocation problems. This issue may happen if there is insufficient memory or the memory usage is limited. The problem is caused by the return value `rc,` which is initialized to SSH_ERROR and later rewritten to save the return value of the function call `pki_key_check_hash_compatible.` The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them calls `goto error` returning SSH_OK.
Severity ?
No CVSS data available.
