Technical Analysis
The vulnerability in jahlives openssl_encrypt before version 1.4.9 involves incorrect default file permissions in the desktop GUI component. When decrypted plaintext files are written, they are assigned world-readable permissions, enabling any local user on the system to access sensitive decrypted data. This issue arises from insecure permission settings rather than a flaw in the cryptographic process itself.
Potential Impact
Unprivileged local users on multi-user systems can read decrypted plaintext files created by the vulnerable GUI, potentially exposing sensitive information. This compromises confidentiality of the decrypted data but does not indicate remote exploitation or privilege escalation.
Mitigation Recommendations
A fix is available in jahlives openssl_encrypt version 1.4.9 and later. Users should upgrade to version 1.4.9 or newer to ensure that decrypted output files are created with secure permissions. No other mitigation guidance is provided.
