Overview
Affected versions of this package are vulnerable to Improper Certificate Validation through incorrect assignment of trusted use instead of a rejected use for a certificate when using the -addreject option with the openssl x509 application. If a user intends to make a trusted certificate rejected for a particular use, it will instead be marked as trusted for that use.
Note: This issue only affects users who use the trusted certificate format and use the openssl x509 command-line application to add rejected uses.
