- Details

A vulnerability was found in libssh, where the authentication check of the connecting client can be bypassed in the
pki_verify_data_signaturefunction 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 valuerc,which is initialized to SSHERROR and later rewritten to save the return value of the function callpki_key_check_hash_compatible.The value of the variable is not changed between this point and the cryptographic verification. Therefore any error between them callsgoto errorreturning SSHOK. - References
