Astronomer Certified security

danger

No versions of Astronomer Certified (AC) are currently supported by Astronomer. Astronomer stopped releasing new versions of AC with the release of Apache Airflow 2.4. Astronomer recommends creating all new Deployments with Astro Runtime, as well as migrating existing Deployments from AC to Astro Runtime as soon as your organization is ready. See Migrate to Runtime and Runtime image architecture.

This page is the source of truth for any Common Vulnerabilities and Exposures (CVEs) identified within any of our supported Astronomer Certified images for Apache Airflow.

You can find information about supported Astronomer Certified images in the following locations:

Refer to Upgrade Apache Airflow on Astronomer for detailed guidelines on how to upgrade between Airflow versions on your Software instance.

This affects the package celery before 5.2.2. It by default trusts the messages and metadata stored in backends (result stores). When reading task metadata from the backend, the data is deserialized. Given that an attacker can gain access to, or somehow manipulate the metadata within a celery backend, they could trigger a stored command injection vulnerability and potentially gain further access to the system. (Details)Use Docker image with one of the following AC Versions:
  • 2.2.3-2
  • 2.2.2-2
  • 2.2.1-3

  • 1.10.5-1 to 1.10.5-6
Server or client applications that call the SSL_check_chain() function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signature_algorithms_cert" TLS extension.
The crash occurs if an invalid or unrecognized signature algorithm is received from the peer. This could be exploited by a malicious peer in a Denial of Service attack. OpenSSL version 1.1.1d, 1.1.1e, and 1.1.1f are affected by this issue. This issue did not affect OpenSSL versions prior to 1.1.1d. Fixed in OpenSSL 1.1.1g (Affected 1.1.1d-1.1.1f). (Details)		Use Docker image with one of the following AC Versions:
  • 1.10.7-10
  • 1.10.5-7
