CVE-2022-2097 : Vulnerability Insights and Analysis
Discover details of CVE-2022-2097, a vulnerability in OpenSSL affecting versions 3.0.0-3.0.4 & 1.1.1-1.1.1p. Learn about the impact, affected systems, and mitigation steps.
AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation may not encrypt the data entirely under certain circumstances, potentially revealing sixteen bytes of preexisting memory data. The vulnerability does not impact OpenSSL's support for OCB-based cipher suites for TLS and DTLS.
Understanding CVE-2022-2097
This CVE highlights a vulnerability in the AES OCB mode that affects specific versions of OpenSSL.
What is CVE-2022-2097?
CVE-2022-2097 exposes a flaw in the AES OCB implementation, potentially revealing sensitive data due to incomplete encryption under certain conditions.
The Impact of CVE-2022-2097
The vulnerability could lead to the exposure of sixteen bytes of preexisting memory data, especially in cases of 'in place' encryption. However, OpenSSL's lack of support for OCB-based cipher suites for TLS and DTLS renders these protocols unaffected.
Technical Details of CVE-2022-2097
The CVE description, affected systems, and exploitation mechanism are vital to understanding the implications of this vulnerability.
