CVE-2013-4237, BZ #14699: Buffer overflow in readdir_r
* sysdeps/posix/dirstream.h (struct __dirstream): Add errcode
member.
* sysdeps/posix/opendir.c (__alloc_dir): Initialize errcode
member.
* sysdeps/posix/rewinddir.c (rewinddir): Reset errcode member.
* sysdeps/posix/readdir_r.c (__READDIR_R): Enforce NAME_MAX limit.
Return delayed error code. Remove GETDENTS_64BIT_ALIGNED
conditional.
* sysdeps/unix/sysv/linux/wordsize-64/readdir_r.c: Do not define
GETDENTS_64BIT_ALIGNED.
* sysdeps/unix/sysv/linux/i386/readdir64_r.c: Likewise.
* manual/filesys.texi (Reading/Closing Directory): Document
ENAMETOOLONG return value of readdir_r. Recommend readdir more
strongly.
* manual/conf.texi (Limits for Files): Add portability note to
NAME_MAX, PATH_MAX.
(Pathconf): Add portability note for _PC_NAME_MAX, _PC_PATH_MAX.

+POSIX-1.2008 does not guarantee that @code{readdir} is thread-safe,
+even when access to the same @var{dirstream} is serialized. But in

Fix stack overflow due to large AF_INET6 requests
Resolves #16072 (CVE-2013-4458).
This patch fixes another stack overflow in getaddrinfo when it is
called with AF_INET6. The AF_UNSPEC case was fixed as CVE-2013-1914,
but the AF_INET6 case went undetected back then.

Date: Mon Sep 23 00:52:09 2013 -0400
BZ #15754: CVE-2013-4788
The pointer guard used for pointer mangling was not initialized for
static applications resulting in the security feature being disabled.
The pointer guard is now correctly initialized to a random value for
static applications. Existing static applications need to be
recompiled to take advantage of the fix.
The test tst-ptrguard1-static and tst-ptrguard1 add regression
coverage to ensure the pointer guards are sufficiently random
and initialized to a default value.
