The glob implementation in the GNU C Library (aka glibc or libc6) allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632.

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

  - The glob implementation in the GNU C Library (aka glibc or libc6) allows remote authenticated users to     cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any     pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different     vulnerability than CVE-2010-2632. (CVE-2010-4756)

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