uuid is vulnerable to Out-of-bounds Write
61
Medium Risk
This Affects:
uuidTL;DR
The UUID functions v3(), v5(), and v6() could write past the end of a caller-provided buffer when given an invalid offset, because they did not validate that the 16-byte UUID fit within buf.length. The fix adds explicit bounds checks and throws a RangeError when the requested byte range is outside the buffer.
Who does this affect?
If you use v3(), v5(), or v6() with a caller-supplied Uint8Array and an attacker-controlled or otherwise invalid offset, you could be affected prior to this patch version.
Background info
uuid is vulnerable to Out-of-bounds Write in versions 0.0.1 - 13.0.0.
How to fix this
Upgrade the org.webjars.npm:uuid library to the patch version or replace the vulnerable function calls with secure alternatives like v4().
