As both libthread_db and pretty printers have the same attack surface (*) as
	DWARF expression overflow
	http://cve.mitre.org/cgi-bin/cvename.cgi?name=2006-4146
where this CVE lists all public GNU/Linux vendors I do not think such security
requirement is Fedora specific.

(*) That is a foreign binary which is enough to just load into GDB.

OTOH the other attack
	.gdbinit current directory execution
	http://cve.mitre.org/cgi-bin/cvename.cgi?name=2005-1705
also lists multiple GNU/Linux vendors and the issue is not yet fixed in FSF
GDB.  But this is IMO just still work in prograss / unfinished, not rejected:
	[RFA] .gdbinit security (revived) [incl doc]
	http://sourceware.org/ml/gdb-patches/2010-11/msg00276.html


Thanks,
Jan
