Описание
Improper certificate validation in PKCS7_verify() in AWS-LC allows an unauthenticated user to bypass certificate chain verification when processing PKCS7 objects with multiple signers, except the final signer.
Customers of AWS services do not need to take action. Applications using AWS-LC should upgrade to AWS-LC version 1.69.0.
A flaw was found in aws-lc, a cryptographic library. An unauthenticated attacker can exploit improper certificate validation within the PKCS7_verify() function. This allows them to bypass the verification process for certificate chains when handling PKCS7 objects that contain multiple digital signers, except for the last one. The primary consequence is a compromise of integrity, as the system may incorrectly trust unverified certificates.
