Description

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.

Affected products

• Node.js: before 0.11.9 — fixed in 0.11.9
• Sync-Exec Project Sync-Exec: through 0.6.2

How to fix

Upgrade to a fixed version: Node.js 0.11.9. Check the vendor advisory for mitigations.
