Notes

http://www.openwall.com/lists/oss-security/2016/01/19/9
Fixed by http://sourceforge.net/p/libdwarf/code/ci/a05f5e2ae6a5f34daa566975894fc2803d6ec684
Reasoning for "unimportant" severity: The affected source code is present
in dwarfdump/, but in the binary package is installed dwarfdump2/ .
dwarfdump2 (the C++ implentation) has been abandoned again by upstream in
fawour of the C version.
