Gentoo Linux Security Advisory

Title: mtr: Stack-based buffer overflow (GLSA 200806-01)
Severity: high
Exploitable: remote
Date: June 03, 2008
Bug(s): #223017
ID: 200806-01

Synopsis


A stack-based buffer overflow was found in mtr, possibly resulting in the
execution of arbitrary code.


Background


mtr combines the functionality of the 'traceroute' and 'ping' programs
in a single network diagnostic tool.


Affected Packages

Package: net-analyzer/mtr
Vulnerable: < 0.73-r1
Unaffected: >= 0.73-r1
Architectures: All supported architectures


Description


Adam Zabrocki reported a boundary error within the split_redraw()
function in the file split.c, possibly leading to a stack-based buffer
overflow.


Impact


A remote attacker could use a specially crafted resolved hostname to
execute arbitrary code with root privileges. However, it is required
that the attacker controls the DNS server used by the victim, and that
the "-p" (or "--split") command line option is used.


Workaround


There is no known workaround at this time.


Resolution


All mtr users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/mtr-0.73-r1"


References

CVE-2008-2357
