CVE-2023-2975 : What You Need to Know

This CVE-2023-2975 pertains to a vulnerability in the AES-SIV cipher implementation within OpenSSL that causes it to ignore empty associated data entries, leading to potential security issues.

Understanding CVE-2023-2975

This vulnerability impacts applications that utilize the AES-SIV algorithm and attempt to authenticate empty data entries as associated data. The bug allows these empty entries to be disregarded by the OpenSSL implementation, potentially resulting in misleading authentication processes.

What is CVE-2023-2975?

The issue lies in the AES-SIV cipher implementation within OpenSSL, where empty associated data entries are not properly authenticated. Applications that rely on this authentication method may be susceptible to manipulation due to the bug.

The Impact of CVE-2023-2975

While the vulnerability is classified as low severity, it could lead to security vulnerabilities in applications that authenticate empty data entries as associated data. The OpenSSL implementation failing to authenticate these entries poses a risk to the integrity of the encryption process.

Technical Details of CVE-2023-2975

This section delves into specific technical aspects of the vulnerability, shedding light on its nature and potential implications.

Vulnerability Description
