Incomplete blacklist vulnerability in nrpc.c in Nagios Remote Plug-In Executor (NRPE) before 2.14 might allow remote attackers to execute arbitrary shell commands via "$()" shell metacharacters, which are processed by bash.
Nagios NRPE 3.2.1 has a Heap-Based Buffer Overflow, as demonstrated by interpretation of a small negative number as a large positive number during a bzero call.
Nagios NRPE 3.2.1 has Insufficient Filtering because, for example, nasty_metachars interprets \n as the character \ and the character n (not as the \n newline sequence). This can cause command injection.
