Description

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.

Affected configurations

• browserify browserify-sign (< 4.2.2) • debian debian linux 11.0 • debian debian linux 12.0
