Sync-exec is a valuable npm package providing synchronous execution capabilities with robust status code support, eliminating external dependencies and the need for node-gyp compilations, making it a lightweight and easily integrable solution. Examining versions 0.6.1 and 0.6.2 reveals subtle but potentially impactful improvements for developers needing synchronous execution. While both versions share the same core description, dependency on coffee-script, MIT license, repository, and author, the key difference lies in the release date. Version 0.6.2 was released on August 24, 2015, whereas version 0.6.1 came out on July 21, 2015. This indicates that version 0.6.2 likely incorporates bug fixes or minor enhancements implemented after the 0.6.1 release. Developers should prefer version 0.6.2 as it represents the more recent and potentially more stable iteration. The 'dist' section allows developers to easily download the package. For developers requiring synchronous execution without the complexities of asynchronous callbacks, sync-exec offers a clean and efficient solution. The package's simplicity, indicated by its lack of external dependencies, ensures straightforward integration into projects and avoids potential dependency conflicts. Consider using the latest available version as it benefits from all previous improvements.

Tmp files readable by other users in sync-exec
Affected versions of sync-exec use files located in /tmp/ to buffer command results before returning values. As /tmp/ is almost always set with world readable permissions, this may allow low privilege users on the system to read the results of commands run via sync-exec under a higher privilege user.
There is currently no direct patch for sync-exec, as the child_process.execSync function provided in Node.js v0.12.0 and later provides the same functionality natively.
The best mitigation currently is to update to Node.js v0.12.0 or later, and migrate all uses of sync-exec to child_process.execSync().
