SCA: security update for pulsar-client (GHSA-5r3h-c3r7-9w4h)

high Tenable Self-Hosted Container Security Plugin ID 410992

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- The Apache Pulsar C++ Client does not verify peer TLS certificates when making HTTPS calls for the
OAuth2.0 Client Credential Flow, even when tlsAllowInsecureConnection is disabled via configuration. This
vulnerability allows an attacker to perform a man in the middle attack and intercept and/or modify the GET
request that is sent to the ClientCredentialFlow 'issuer url'. The intercepted credentials can be used to
acquire authentication data from the OAuth2.0 server to then authenticate with an Apache Pulsar cluster.
An attacker can only take advantage of this vulnerability by taking control of a machine 'between' the
client and the server. The attacker must then actively manipulate traffic to perform the attack. The
Apache Pulsar Python Client wraps the C++ client, so it is also vulnerable in the same way. This issue
affects Apache Pulsar C++ Client and Python Client versions 2.7.0 to 2.7.4; 2.8.0 to 2.8.3; 2.9.0 to
2.9.2; 2.10.0 to 2.10.1; 2.6.4 and earlier. Any users running affected versions of the C++ Client or the
Python Client should rotate vulnerable OAuth2.0 credentials, including client_id and client_secret. 2.7
C++ and Python Client users should upgrade to 2.7.5 and rotate vulnerable OAuth2.0 credentials. 2.8 C++
and Python Client users should upgrade to 2.8.4 and rotate vulnerable OAuth2.0 credentials. 2.9 C++ and
Python Client users should upgrade to 2.9.3 and rotate vulnerable OAuth2.0 credentials. 2.10 C++ and
Python Client users should upgrade to 2.10.2 and rotate vulnerable OAuth2.0 credentials. 3.0 C++ users are
unaffected and 3.0 Python Client users will be unaffected when it is released. Any users running the C++
and Python Client for 2.6 or less should upgrade to one of the above patched versions. (CVE-2022-33684)
