Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 ESM / 20.04 ESM / 22.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5847-1 advisory.

 It was discovered that Grunt was not properly loading YAML files before parsing them. An attacker could possibly use this issue to execute arbitrary code. (CVE-2020-7729)

 It was discovered that Grunt was not properly handling symbolic links when performing file copy operations. An attacker could possibly use this issue to expose sensitive information or execute arbitrary code. (CVE-2022-0436)

 It was discovered that there was a race condition in the Grunt file copy function, which could lead to an arbitrary file write. An attacker could possibly use this issue to perform a local privilege escalation attack or to execute arbitrary code. (CVE-2022-1537)

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

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