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

  - Insufficient validation of environment variables in the telnet client supplied in Junos OS can lead to     stack-based buffer overflows, which can be exploited to bypass veriexec restrictions on Junos OS. A stack-     based overflow is present in the handling of environment variables when connecting via the telnet client     to remote telnet servers. This issue only affects the telnet client  accessible from the CLI or shell     in Junos OS. Inbound telnet services are not affected by this issue.
