Denial of Service (DoS)

bignum is an Arbitrary precision integral arithmetic for Node.js using OpenSSL.

This library is based on node-bigint by substack, but instead of using libgmp, it uses the builtin bignum functionality provided by OpenSSL. The advantage is that OpenSSL is already part of Node.js, so this library does not add any external dependency whatsoever.

Affected versions of this package are vulnerable to Denial of Service (DoS) due to a type-check exception in V8, when verifying the type of the second argument to the .powm function, V8 will crash regardless of Node try/catch blocks.

How to fix Denial of Service (DoS)?

There is no fixed version for bignum.
