CVE-2018-7166 (GCVE-0-2018-7166)

Vulnerability from cvelistv5 – Published: 2018-08-21 13:00 – Updated: 2024-09-17 00:26

Summary
In all versions of Node.js 10 prior to 10.9.0, an argument processing flaw can cause `Buffer.alloc()` to return uninitialized memory. This method is intended to be safe and only return initialized, or cleared, memory. The third argument specifying `encoding` can be passed as a number, this is misinterpreted by `Buffer's` internal "fill" method as the `start` to a fill operation. This flaw may be abused where `Buffer.alloc()` arguments are derived from user input to return uncleared memory blocks that may contain sensitive information.
Severity
