Name of the Vulnerable Software and Affected Versions
openssl encrypt versions prior to 1.4.9
Description
Insufficient validation of key derivation function (KDF) costs in crafted files allows attackers to trigger unbounded memory and CPU exhaustion during pre-authentication processing. By supplying malicious files with excessive KDF parameters, an attacker can exhaust system resources, leading to a process crash or hang before password verification takes place.
Recommendations
Update to version 1.4.9 or later.
