* A stack-based buffer overflow was found in libresolv when invoked from
libnss_dns, allowing specially crafted DNS responses to seize control
of execution flow in the DNS client. The buffer overflow occurs in
the functions send_dg (send datagram) and send_vc (send TCP) for the
NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
family. The use of AF_UNSPEC triggers the low-level resolver code to
send out two parallel queries for A and AAAA. A mismanagement of the
buffers used for those queries could result in the response of a query
writing beyond the alloca allocated buffer created by
_nss_dns_gethostbyname4_r. Buffer management is simplified to remove
the overflow. Thanks to the Google Security Team and Red Hat for
reporting the security impact of this issue, and Robert Holiday of
Ciena for reporting the related bug 18665. (CVE-2015-7547)

One common case of __GNUC_PREREQ (4, 7) conditionals is use of
diagnostic control pragmas for -Wmaybe-uninitialized, an option
introduced in GCC 4.7 where older GCC needed -Wuninitialized to be
controlled instead if the warning appeared with older GCC. This patch
removes such conditionals.
(There remain several older uses of -Wno-uninitialized in makefiles
that still need to be converted to diagnostic control pragmas if the
issue is still present with current sources and supported GCC
versions, and it's likely that in most cases those pragmas also will
end up controlling -Wmaybe-uninitialized.)
Tested for x86_64 and x86 (testsuite, and that installed stripped
shared libraries are unchanged by the patch, except for libresolv
since res_send.c contains assertions whose line numbers are changed by
the patch).

Remove use of ext.nsmap member of struct __res_state and always use
an identity mapping betwen the nsaddr_list array and the ext.nsaddrs
array. The fact that a nameserver has an IPv6 address is signalled by
setting nsaddr_list[].sin_family to zero.
I see this warning in my build on F21 x86_64, which seems to be due to
a weak check for array bounds. Fixed by making the bounds check
stronger.
This is not an actual bug since nscount is never set to anything
greater than MAXNS. The compiler however does not know this, so we
need the stronger bounds check to quieten the compiler.
In send_vc function at resolv/res_send.c, There is the
following warning on some architectures:
'resplen' may be used uninitialized in this function
[-Wmaybe-uninitialized]
And this is a false positive. This patch suppress the
compiler warning.
[Fixes BZ #14308, #12994, #13651]
AF_UNSPEC results in sending two queries in parallel, one for the A
record and the other for the AAAA record. If one of these is a
referral, then the query fails, which is wrong. It should return at
least the one successful response.
The fix has two parts. The first part makes the referral fall back to
the SERVFAIL path, which results in using the successful response.
There is a bug in that path however, due to which the second part is
necessary. The bug here is that if the first response is a failure
and the second succeeds, __libc_res_nsearch does not detect that and
assumes a failure. The case where the first response is a success and
the second fails, works correctly.
This condition is produced by buggy routers, so here's a crude
interposable library that can simulate such a condition. The library
overrides the recvfrom syscall and modifies the header of the packet
received to reproduce this scenario. It has two key variables:
mod_packet and first_error.
The mod_packet variable when set to 0, results in odd packets being
modified to be a referral. When set to 1, even packets are modified
to be a referral.
The first_error causes the first response to be a failure so that a
domain-appended search is performed to test the second part of the
__libc_nsearch fix.
The driver for this fix is a simple getaddrinfo program that does an
AF_UNSPEC query. I have omitted this since it should be easy to
implement.
I have tested this on x86_64.
The interceptor library source:
/* Override recvfrom and modify the header of the first DNS response to make it
a referral and reproduce bz #845218. We have to resort to this ugly hack
because we cannot make bind return the buggy response of a referral for the
AAAA record and an authoritative response for the A record. */

define it. It also make adjustments in code where tests checked if macro

There is some more shardware/software out there which has problems
if two DNS requests are sent using the same tuple
(source addr, source port, dest addr, dest port)
This can range from firewalls to load balancers. Some of the vendors

the other way round.
* resolv/Makefile (libresolv-routines): Add base64, inet_net_ntop,
inet_net_pton, inet_net.
* resolv/arpa/nameser.h (__BIND): Update version number.
Mon Aug 12 19:03:22 1996 Thomas Bushnell n/BSG <thomas@psilocin.gnu.ai.mit.edu>
* sysdeps/generic/gnu/types.h: Declare __fd_mask as `unsigned long'.
* mach/Makefile (mach/mach_host.uh): Depend on
$(objpfx)/mach-syscalls.mk.
($(objpfx)mach-shortcuts.h): Depend on $(objpfx)mach/mach_host.h.
(This fixes a make loop; thanks to Marcus Daniels
<marcus@sysc.pdx.edu> for the patch.)
* sysdeps/mach/hurd/errnos.awk: Move EWOULDBLOCK check before errno==0
check. mib's clueless hacking broke it.
Thu Jul 18 04:27:21 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>
* Makerules ($(libdir)/libc.so): Add missing / after $(cryptobjdir).
Wed Jul 17 10:54:20 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/alpha/start.S: Move to ...
* sysdeps/alpha/elf/start.S: here.
* misc/sys/ustat.h: New file.
* misc/ustat.h: Ditto.
* sysdeps/generic/ustatbits.h: Ditto.
* libc-orig/sysdeps/stub/ustat.c: Ditto.
* sysdeps/unix/sysv/linux/ustatbits.h: Ditto.
* misc/Makefile (headers): Mention ustat.h, sys/ustat.h, and
ustatbits.h.
(routines): Mention ustat.
* sysdeps/unix/sysv/linux/syscalls.list: Mention klogctl in
alphabetically correct place. Mention ustat.
* sysdeps/unix/alpha/sysdep.S: Make errno a bss symbol, not a
common symbol (makes errno accessible from gdb).
* login/pututline_r.c (pututline_r): Test ut_id in repositioning
test, not ut_type.
* login/logwtmp.c (logwtmp): Reimplemented. Must ensure that a
record always gets appended at end of file (wtmp is a log file,
after all). Set ut_type to DEAD_PROCESS if name is empty.
* login/getutid_r.c (getutid_r): Handle search for UT_TYPE in
separate loop from search for UT_ID. Fix code so it is in
sync with Unix man page.
* login/getutline_r.c (getutline_r): Stop searching only if
ut_line matches and type is either USER_PROCESS or LOGIN_PROCESS.
Tue Jul 16 15:06:18 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/netinet/in.h: Base on <linux/in.h> to
avoid duplicate declarations.
Sun Jul 14 19:08:55 1996 David Mosberger-Tang <davidm@azstarnet.com>
* manual/maint.texi (Supported Configurations): Add alpha-gnu-linux
and alpha-gnu-linuxecoff targets.
Fri Jul 12 16:58:44 1996 David Mosberger-Tang <davidm@azstarnet.com>
* sysdeps/unix/sysv/linux/netinet/in.h: Declare bindresvport().
Sat Jun 22 23:30:07 1996 David Mosberger-Tang <davidm@azstarnet.com>
* resolv/res_send.c (res_send): Declare FROMLEN as size_t instead
of int.
* resolv/res_comp.c (res_hnok): Use empty statement in place
of NULL (which generates a "useless expression" warning in
gcc).
* inet/netdb.h: Moved to resolv.
* inet/Makefile (headers): Remove netdb.h.
* resolv/Makefile (headers): Add netdb.h.
* resolv/gethnamaddr.c, resolv/inet_addr.c, resolv/netdb.h,
resolv/res_send.c: Updated from BIND-4.9.3-BETA26.
* hurd/thread-cancel.c: If SS->cancel_hook is not null, call it before
resuming the thread.
* hurd/hurd/signal.h (struct hurd_sigstate): New member `cancel_hook'.
* hurd/Makefile: Removed dep on hurd/signal.h for RPC stub objects.
Mon Aug 21 16:37:09 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* sysdeps/i386/dl-machine.h (elf_machine_rel): Grok R_386_NONE
relocs, and do nothing. Why the linker generates them we may
never know.
* sysdeps/mach/hurd/i386/intr-msg.h: New file.
