HIGH7.5EPSS 0.01%PKCS7_verify Signature Validation Bypass in AWS-LC
發布日:2026/3/3修改日:2026/3/21
描述
Improper signature validation in `PKCS7_verify()` in AWS-LC allows an unauthenticated user to bypass signature verification when processing PKCS7 objects with Authenticated Attributes. Customers of AWS services do not need to take action. `aws-lc-sys` contains code from AWS-LC. Applications using `aws-lc-sys` should upgrade to the most recent release of `aws-lc-sys`. There is no workaround; applications using `aws-lc-sys` should upgrade to the most recent release of `aws-lc-sys`.
