Hi,

The following vulnerability was published for node-browserify-sign.

CVE-2023-46234[0]:
| browserify-sign is a package to duplicate the functionality of
| node's crypto public key functions, much of this is based on Fedor
| Indutny's work on indutny/tls.js. An upper bound check issue in
| `dsaVerify` function allows an attacker to construct signatures that
| can be successfully verified by any public key, thus leading to a
| signature forgery attack. All places in this project that involve
| DSA verification of user-input signatures will be affected by this
| vulnerability. This issue has been patched in version 4.2.2.
