What is CRYPT32 DLL?
The Microsoft Cryptographic library CRYPT32. DLL is the module that implements many of the certificate and cryptographic messaging functions in the CryptoAPI. This library comes with the Windows and Windows Server Operating Systems.
What is a CVE patch?
The CVE (Common Vulnerabilities and Exposures) number is a unique identifier used by vendors such as Microsoft, RedHat, and Adobe to catalog individual vulnerabilities where patches are provided as a resolution. “Therefore, it is an unbiased and independent database for all vendors to publish their vulnerabilities.”
What are operating system vulnerabilities?
A vulnerability is effectively an error in the code or the logic of operation within the OS or the application software. Because today’s OSs and applications are very complex and include a lot of functionality, it’s difficult for a vendor’s development team to create software that contains no errors.
