Summary

Versions of `bl` before 0.9.5 and 1.0.1 are vulnerable to memory exposure.

`bl.append(number)` in the affected `bl` versions passes a number to Buffer constructor, appending a chunk of uninitialized memory

## Recommendation

Update to version 0.9.5, 1.0.1 or later.

Patch / fix

  • npm bl 0.9.5, 1.0.1

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
