Technical Details of CVE-2022-29202
Explore the specific technical aspects of the CVE-2022-29202 vulnerability in TensorFlow.
Vulnerability Description
The flaw in
tf.ragged.constant
allows an attacker to trigger a denial of service condition by depleting system memory, affecting versions prior to 2.9.0, 2.8.1, 2.7.2, and 2.6.4.
Affected Systems and Versions
The issue impacts TensorFlow versions < 2.6.4, >= 2.7.0rc0 and < 2.7.2, >= 2.8.0rc0 and < 2.8.1, and >= 2.9.0rc0 and < 2.9.0, urging users to update to patched versions.
Exploitation Mechanism
Attackers can exploit the lack of input validation in
tf.ragged.constant
to exhaust all available memory, executing a denial of service attack.
Mitigation and Prevention
Discover the necessary steps to mitigate the risks associated with CVE-2022-29202 and prevent similar vulnerabilities in the future.
Immediate Steps to Take
Users are advised to update TensorFlow to versions 2.9.0, 2.8.1, 2.7.2, or 2.6.4, which contain patches addressing the memory consumption issue.
Long-Term Security Practices
Implement robust input validation mechanisms and consistently monitor security advisories to safeguard against potential threats like uncontrolled resource consumption.
Patching and Updates
