GHSA-hfpc-8r3f-gw53 — AWS-LC has PKCS7_verify Signature Validation Bypass

Affected: crates.io: aws-lc-sys

### Summary AWS-LC is an open-source, general-purpose cryptographic library.

### Impact 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.

#### Impacted versions: aws-lc-sys versions: >= 0.24.0, < 0.38.0

### Patches The patch is included in v0.38.0

### Workarounds There is no workaround. Applications using aws-lc-sys should upgrade to the most recent release of aws-lc-sys.
