Package : node-trim-newlines
Version : 1.0.0-1+deb10u1
CVE ID : CVE-2021-33623

It was discovered that there was a potential remote denial of service
vulnerability in node-trim-newlines, a Javascript module to strip
newlines from the start and/or end of a string.

This regular expression Denial of Service (ReDoS) attack exploited
the fact that most Regular Expression implementations can reach
extreme situations that cause them to work very slowly in a way that
is exponentially related to the input size. An attacker can then
cause a program using node-trim-newlines (and thus the offending
regex) to enter one of these extreme situations and then hang for a
very long time.

For Debian 10 buster, this problem has been fixed in version
1.0.0-1+deb10u1.

We recommend that you upgrade your node-trim-newlines packages.
