Vulnerability Name:

CVE-2017-16024 (CCN-145660)

Assigned:2017-04-15
Published:2017-04-15
Updated:2019-10-09
Summary:The sync-exec module is used to simulate child_process.execSync in node versions <0.11.9. Sync-exec uses tmp directories as a buffer before returning values. Other users on the server have read access to the tmp directory, possibly allowing an attacker on the server to obtain confidential information from the buffer/tmp file, while it exists.
