Name of the Vulnerable Software and Affected Versions
openssl encrypt versions prior to 1.4.9
Description
The software fails to enforce a time ceiling on key derivation function (KDF) iteration counts specified in file metadata. A KDF is a cryptographic algorithm that derives one or more secret keys from a master password. Attackers can craft files with extremely high KDF iteration counts to consume CPU resources for unbounded periods before password verification occurs.
Recommendations
Update to version 1.4.9 or later.
