libcurl.so is vulnerable to Information Disclosure. The SSH server’s public key is verified with the use of a SHA 256 hash functionality provided by the library, however if the check is unsuccessful, the fingerprint’s memory will be released before an error message is returned. This issue puts users at risk of seeing or learning about private heap-based data that could have been inserted into the error message.
