Astronomer Certified security

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.

Reporting Vulnerabilities and Security Concerns

Vulnerability reports for Astronomer Certified should be sent to security@astronomer.io. All security concerns, questions and requests should be directed here.

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 2.2.0-5
CVE-2021-33430	2022-01-19	NumPy	2.2.3-1 2.2.2-1 2.2.1-1 to 2.2.1-2 2.2.0-1 to 2.2.0-4 2.1.4-1 to 2.1.4-3 2.1.3-1 to 2.1.3-3 2.1.1-1 to 2.1.1-5 2.1.0-1 to 2.1.0-6	A Buffer Overflow vulnerability exists in NumPy 1.9.x in the PyArray_NewFromDescr_int function of `ctors.c` when specifying arrays of large dimensions (over 32) from Python code, which could let a malicious user cause a Denial of Service. (Details)	Use Docker image with one of the following AC Versions: 2.2.3-2 2.2.2-2 2.2.1-3 2.2.0-5 2.1.4-4 2.1.3-4 2.1.1-6 2.1.0-7

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
CVE-2019-16168	2019-09-09	SQLite	Alpine images with following AC Versions: 1.10.7-1 to 1.10.7-8 1.10.5-1 to 1.10.5-6	In SQLite through 3.29.0, whereLoopAddBtreeIndex in `sqlite3.c` can crash a browser or other application because of missing validation of a `sqlite_stat1` sz field, aka a “severe division by zero in the query planner.” (Details)	Use Docker image with one of the following AC Versions: 1.10.7-10 1.10.5-7
