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

  - Versions of the package cross-spawn before 6.0.6, from 7.0.0 and before 7.0.5 are vulnerable to Regular
    Expression Denial of Service (ReDoS) due to improper input sanitization. An attacker can increase the CPU
    usage and crash the program by crafting a very large and well crafted string. (CVE-2024-21538)

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