CVE-2021-33147
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImproper conditions check in the Intel(R) IPP Crypto library before version 2021.2 may allow an authenticated user to potentially enable information disclosure via local access.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceImproper conditions check in Intel(R) IPP Crypto library before version 2021.2 allows an authenticated user with local access to potentially enable information disclosure. The vulnerability stems from a logic error in conditional checking within the crypto library.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate Intel IPP Crypto library filesSearch system for DLL files matching ippcv or ipp_crypto patterns (e.g., ippcv*.dll, libippcv*.so). Check common installation directories: Program Files, /opt, /usr/lib, or application-specific paths.Affected if Intel IPP Crypto library files are present on the system
-
Identify library versionRight-click the located DLL/SO file, select Properties, then Details tab to view File Version. Alternatively, use command line: 'strings <library_file> | grep -i version' or a tool like dumpbin/strings to extract version metadata.Affected if Version displayed is below 2021.2 or version cannot be determined (may indicate vulnerable older release)
-
Confirm library is in useCheck running processes or application dependencies that link to Intel IPP Crypto. On Windows: use Process Explorer or 'tasklist /m | findstr ippcv'. On Linux: use 'ldd <application> | grep ippcv' or 'lsof' on running processes.Affected if Applications or processes are actively using Intel IPP Crypto library version below 2021.2
System is affected if Intel IPP Cryptography library version below 2021.2 is installed and actively in use by any application.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2021.2
Update Intel IPP Crypto library to version 2021.2 or later to remediate the vulnerability.
2021.2
- Identify the current version of Intel IPP Cryptography installed in your environment
- Download Intel IPP Cryptography version 2021.2 or later from the official Intel website (www.intel.com)
- Follow Intel's standard upgrade procedure for Intel IPP Cryptography
- Verify the installed version is 2021.2 or later to confirm the remediation
