High (8.7) in jahlives openssl encrypt. EPSS 0.5% chance of exploitation in the next 30 days. Fixed in openssl-encrypt 1.4.9.
openssl_encrypt versions before 1.4.9 fail to properly validate key derivation function costs in crafted files, allowing attackers to trigger unbounded memory and CPU exhaustion during pre-authentication processing. Attackers can supply malicious files with excessive KDF parameters to exhaust system resources and crash or wedge the process before password verification occurs.
