Apache Arrow PyArrow Arbitrary Code Execution Vulnerability (CVS 2023-47248) Notification

novembro 15, 2023 | NSFOCUS


Recently, NSFOCUS CERT found that Apache Arrow issued a security notice, which fixed an arbitrary code execution vulnerability in the PyArrow library (CVE-2023-47248). Due to PyArrow reading Arrow IPC, Feather, or Parquet data from untrusted sources, PyExtensionType creates an automatic loading feature that allows for deserialization of data from non PyArrow sources. When using PyExtensionType to create PyArrow specific extension types, attackers can achieve arbitrary code execution on the target system by constructing malicious data packets. At present, the details of the vulnerability have been disclosed in public. Affected users should take protective measures as soon as possible.
