- Summary
- browserify-sign vulnerable via an upper bound check issue in `dsaVerify` that leads to a signature forgery attack
- Details
-
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
dsaVerifyfunction 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. - Database specific
