swift-crypto vulnerabilities

A remote attacker may be able to terminate a process that passes attacker-controlled input to the P-384 VOPRF API without bounding its length. This vulnerability is addressed in swift-crypto version 5.0.3.

In the swift-crypto library before version 4.5.1, when initializing an RSA public key from DER or PEM bytes fails, a double-free occurs. This can cause a crash on future memory allocations. The issue manifests when BoringSSL cannot decode the key.

A remote attacker can supply a short X-Wing HPKE encapsulated key and trigger an out-of-bounds read in the C decapsulation path, potentially causing a crash or memory disclosure depending on runtime protections. This issue is fixed in swift-crypto version 4.3.1.
