Key facts

Description

Stack-based buffer overflow in the split_redraw function in split.c in mtr before 0.73, when invoked with the -p (aka --split) option, allows remote attackers to execute arbitrary code via a crafted DNS PTR record. NOTE: it could be argued that this is a vulnerability in the ns_name_ntop function in resolv/ns_name.c in glibc and the proper fix should be in glibc; if so, then this should not be treated as a vulnerability in mtr.
