| Package | Affected versions | Patched versions |
|---|---|---|
| openssl-encrypt | < 1.4.9 | 1.4.9 |
| openssl encrypt | < 1.4.9 | 1.4.9 |
openssl_encrypt before 1.4.9 fails to validate the memory_cost parameter from identity file protection blocks, allowing attackers to trigger out-of-memory conditions during key derivation. Attackers with write access to local identity stores can craft malicious identity files with excessive memory_cost values that cause the host to crash when unlocking identities before authentication.
