Overview
Affected versions of this package are vulnerable to Cleartext Storage of Sensitive Information in the process that handles service bindings from VCAP_SERVICES containing TLS client credentials. An attacker can access sensitive private key material by reading temporary files created with default permissions in the /tmp directory.
Note:
This is only exploitable if another process running under a different user ID has access to /tmp within the same container or system.
Workaround
This vulnerability can be mitigated by preventing other processes from running in the container under a different UID with access to /tmp.
