bcrypt
Monthly
JRuby's BCrypt implementation suffers from a signed integer overflow when the cost parameter is set to 31, causing the key-strengthening loop to execute zero iterations and reducing password hashing to a negligible computational cost. Applications using bcrypt-ruby with cost=31 generate seemingly valid hashes that verify correctly but provide virtually no protection against brute-force attacks. No patch is currently available for this vulnerability.
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.
Integer overflow in the crypt_raw method in the key-stretching implementation in jBCrypt before 0.4 makes it easier for remote attackers to determine cleartext values of password hashes via a. Rated medium severity (CVSS 5.0), this vulnerability is remotely exploitable, low attack complexity.
