Summary
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.
Risk Assessment
An attacker can cause a process crash (denial of service), potentially leading to service unavailability. This can disrupt applications relying on swift-crypto.
Recommendation
Update swift-crypto to version 5.0.3 or later. Consider bounding input length at the application level.
Other vulnerabilities in swift-crypto
See all- CVE-2026-43823High
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.
- CVE-2026-28815High
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.
