high Nessus Plugin ID 184063

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 11 / 12 host has a package installed that is affected by a vulnerability as referenced in the dsa-5539 advisory.

- 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. (CVE-2023-46234)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the node-browserify-sign packages.

For the stable distribution (bookworm), this problem has been fixed in version 4.2.1-3+deb12u1.
