login: audit log injection attack via login
A while back I found a couple audit log injection attacks which became
CVE-2007-3102. I forgot to look at login to see if its vulnerable and Mirek
found that it is. To verify the problem, type:
root addr=xyz.com
for the account name while logging in. It will look like root logged in with
an address of xyz.com.

sys-utils: correct setarch.8 manpage link creation
At least on Debian, .so commands are relative to the man directory
(e.g., /usr/share/man), not to the subdirectory:
% man i386
man: can't open /usr/share/man/setarch.8: No such file or directory
No manual entry for i386

hwclock: check for ENODEV
/sbin/hwclock is supposed to fall back to using /dev/rtc0 if /dev/rtc isn't
working (which it isn't, because mkinitrd creates it with the old device
numbers, and we're switching to the new RTC_CLASS driver).
Unfortunately, it'll only cope if the error it gets is ENOENT (i.e. the device
node doesn't exist). It doesn't fall back to the next device in the list if the
error is ENODEV, which is what happens when the device node exists, but there's
no driver.

mkswap: possible to crash with SELinux relabeling support
When fgetfilecon() is failed with -ENODATA, this process does not
exit. However, "oldcontext" is not initialized in this case, so
context_new() will be called with uninitialized "oldcontext" at the
next.
Finally, it makes a segmentation fault, because context_new() have to
refer an incorrect memory region.
The attached patch fixes this matter using matchpathcon(). If we
cannot obtain actual file context due to -ENODATA, a context which is
returned by matchpathcon() is applied as oldcontext. Then, the type
of the context is relabeled to "swapfile_t" explicitly.

script: dies on SIGWINCH
The "doinput" process doesn't make a difference between SIGWINCH and
SIGCHILD. This process also sends unnecessary SIGWINCH to child (the
signal is ignored by child). Fixed.
chsh: should use pam_end function to terminate the PAM transaction
chsh will use PAM transaction if macros 'REQUIRE_PASSWORD' and
'HAVE_SECURITY_PAM_MISC_H' are defined, but there is no pam_end function be
used when the PAM transaction be terminated.
This patch also cleanup PAM code in chsh(1).

Only pull in locale.h as needed and move it to the common nls.h.
mount: chain of symlinks to fstab causes use of pointer after free
Looking at the source in 'mount/realpath.c' we find that when dealing with
the second or later symlink in the chain, a memory block was free()d before
copying its contents to a newly allocated block.
