mtr split_redraw() buffer overflow
|mtr-splitredraw-bo (42535)||High Risk|
mtr is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the split_redraw function when the -p or --split option is enabled. By persuading a victim to connect to a DNS server containing a specially-crafted host name, a remote attacker could overflow a buffer and execute arbitrary code with elevated privileges or cause the application to crash.
Upgrade to the latest version of Mtr (0.73 or later), available from the Mtr Web site. See References.

- CVE-2008-2357: 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.
