Concurrent Ruby - `ReentrantReadWriteLock` read-count overflow grants a write lock without exclusivity

Summary Concurrent::ReentrantReadWriteLock can incorrectly grant a write lock after one thread acquires the read lock 32,768 times. The lock stores a thread's local read and write hold counts in one integer. The low 15 bits are used for the read hold count, and bit 15 is used as WRITELOCKHELD...

PHP JWT Library: PBES2-HS*+A*KW unwrap accepts an unbounded p2c iteration count, enabling CPU-amplification denial of service

Impact When a JWE uses a password-based key-encryption algorithm PBES2-HS256+A128KW, PBES2-HS384+A192KW, PBES2-HS512+A256KW, PBES2AESKW::unwrapKey reads the p2c PBKDF2 iteration count parameter directly from the attacker-controlled JOSE header and passes it to hashpbkdf2 with no upper bound. The...
