mtr through 0.95, in certain privileged contexts, mishandles execution of a program specified by the MTR_PACKET environment variable. NOTE: mtr on macOS may often have Sudo rules, as an indirect consequence of Homebrew not installing setuid binaries.
Note that we have closed all RHEL trackers for this as NOTABUG because RHEL versions of mtr are not affected to begin with and proposed fix doesn't apply to mtr in RHEL context (i.e. no custom mtr sudo rules are needed).
