Synopsis

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

Description

The remote Debian 10 host has a package installed that is affected by a vulnerability as referenced in the dla-3247 advisory.

- ------------------------------------------------------------------------- Debian LTS Advisory DLA-3247-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb December 23, 2022 https://wiki.debian.org/LTS
- -------------------------------------------------------------------------

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.

For the detailed security status of node-trim-newlines please refer to its security tracker page at:

Solution

Upgrade the node-trim-newlines packages.
