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.
AnalysisAI
Timing side-channel attacks in AWS-LC's AES-CCM decryption implementation allow unauthenticated attackers to infer authentication tag validity through precise timing measurements. The vulnerability affects AWS-LC and related cryptographic libraries across multiple AES-CCM variants (128, 192, and 256-bit), potentially enabling attackers to forge authenticated messages. AWS service customers are unaffected, but applications using AWS-LC directly should upgrade to version 1.69.0 or later.
Technical ContextAI
Affects Aws-Lc-Fips-Sys. 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.
