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

  - zlib versions up to and including 1.3.1.2 include a global buffer overflow in the untgz utility located     under contrib/untgz. The vulnerability is limited to the standalone demonstration utility and does not     affect the core zlib compression library. The flaw occurs when a user executes the untgz command with an     excessively long archive name supplied via the command line, leading to an out-of-bounds write in a fixed-     size global buffer. (CVE-2026-22184)

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