What is CVE-2017-5640?

A vulnerability in Apache Impala allows a malicious process impersonating an Impala daemon to bypass authentication checks when Kerberos is enabled without TLS. If the malicious server prematurely responds with 'COMPLETE' during the SASL handshake, the client perceives the handshake as successful, leaving it vulnerable to unauthorized access and exposing sensitive data.

Affected Version(s)

Apache Impala 2.7.0 to 2.8.0 incubating
