Description:
Adam Zabrocki has discovered a vulnerability in Mtr, which potentially can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the "split_redraw()" function in split.c. This can be exploited to cause a stack-based buffer overflow via a specially crafted resolved hostname.
Successful exploitation may allow execution of arbitrary code, but requires that the attacker controls the DNS server used by the victim, and that the "-p" (or "--split") command line option is used.
The vulnerability is confirmed in version 0.72. Prior versions may also be affected.
Solution:
Update to version 0.73.
Provided and/or discovered by:
Adam Zabrocki
