Stack-based buffer overflow in the splitredraw 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 nsnamentop function in resolv/nsname.c in glibc and the proper fix should be in glibc; if so, then this should not be treated as a vulnerability in mtr.
The mtr program only uses a seteuid call when attempting to drop privileges, which could allow local users to gain root privileges.
