How to Fix CVE-2022-2097

To remediate this vulnerability, upgrade all affected Openssl src dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

openssl-src fixed: 111.22.0

Upgrade openssl-src to 111.22.0

openssl-src fixed: 300.0.9

Upgrade openssl-src to 300.0.9

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release:

inspect dependencies for openssl-src

How to Check if You Are Affected

To determine whether your application is affected by CVE-2022-2097, inspect your project dependencies for Openssl src:

inspect dependencies for openssl-src

Analyze the terminal output to locate any version of Openssl src in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 111.22.0), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-311: Missing Encryption of Sensitive Data, where the product does not encrypt sensitive or critical information before storage or transmission. In Openssl src, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was pre-existing in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected.
