Package        : node-browserify-sign
CVE ID         : CVE-2023-46234
Debian Bug     : 1054667

It was reported that incorrect bound checks in the dsaVerify function
in node-browserify-sign, a Node.js library which adds crypto signing
for browsers, allows an attacker to perform signature forgery attacks
by constructing signatures that can be successfully verified by any
public key.

For the oldstable distribution (bullseye), this problem has been fixed
in version 4.2.1-1+deb11u1.

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

We recommend that you upgrade your node-browserify-sign packages.
