The trim-newlines package before 3.0.1 and 4.x before 4.0.1 for Node.js has an issue related to regular expression denial-of-service (ReDoS) for the .end() method.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The trim-newlines package before 3.0.1 and 4.x before 4.0.1 for Node.js has an issue related to regular     expression denial-of-service (ReDoS) for the .end() method. (CVE-2021-33623)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5999-1 advisory.

    It was discovered that trim-newlines incorrectly handled certain inputs. If a user or an automated system     were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue     to cause a denial of service. (CVE-2021-33623)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

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

    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.
