Timing Side-Channel in AES-CCM Tag Verification in AWS-LC
Résumé
Timing Side-Channel in AES-CCM Tag Verification in AWS-LC
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Observable timing discrepancy in AES-CCM decryption in AWS-LC allows an unauthenticated user to potentially determine authentication tag validity via timing analysis.
The impacted implementations are through the EVP CIPHER API: EVP_aes_128_ccm, EVP_aes_192_ccm, and EVP_aes_256_ccm.
Customers of AWS services do not need to take action. Applications using AWS-LC should upgrade to AWS-LC version 1.69.0.
