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.
