Log message:
update to version 1.8.20p2
upstream changelog:
2017-05-31 Todd C. Miller <Todd.Miller%courtesan.com@localhost>
* NEWS, configure, configure.ac:
Sudo 1.8.20p2
[47836f4c9834]
* src/ttyname.c:
A command name may also contain newline characters so read
/proc/self/stat until EOF. It is not legal for /proc/self/stat to
contain embedded NUL bytes so treat the file as corrupt if we see
any. With help from Qualys.
This is not exploitable due to the /dev traversal changes in sudo
1.8.20p1 (thanks Solar!).

2017-05-30 Todd C. Miller <Todd.Miller%courtesan.com@localhost>
* src/ttyname.c:
Use /proc/self consistently on Linux. As far as I know, only AIX
doesn't support /proc/self.

Log message:
sudo: update to 1.8.20p1.
Fixes CVE-2017-1000367, local privilege escalation on linux.
What's new in Sudo 1.8.20p1
* Fixed "make check" when using OpenSSL or GNU crypt.
Bug #787.
* Fixed CVE-2017-1000367, a bug parsing /proc/pid/stat on Linux
when the process name contains spaces. Since the user has control
over the command name, this could potentially be used by a user
with sudo access to overwrite an arbitrary file on systems with
SELinux enabled. Also stop performing a breadth-first traversal
of /dev when looking for the device; only a hard-coded list of
directories are checked,
What's new in Sudo 1.8.20
* Added support for SASL_MECH in ldap.conf. Bug #764
* Added support for digest matching when the command is a glob-style
pattern or a directory. Previously, only explicit path matches
supported digest checks.
* New "fdexec" Defaults option to control whether a command
is executed by path or by open file descriptor.
* The embedded copy of zlib has been upgraded to version 1.2.11.
* Fixed a bug that prevented sudoers include files with a relative
path starting with the letter 'i' from being opened. Bug #776.
* Added support for command timeouts in sudoers. The command will
be terminated if the timeout expires.
* The SELinux role and type are now displayed in the "sudo -l"
output for the LDAP and SSSD backends, just as they are in the
sudoers backend.
* A new command line option, -T, can be used to specify a command
timeout as long as the user-specified timeout is not longer than
the timeout specified in sudoers. This option may only be
used when the "user_command_timeouts" flag is enabled in sudoers.
* Added NOTBEFORE and NOTAFTER command options to the sudoers
backend similar to what is already available in the LDAP backend.
* Sudo can now optionally use the SHA2 functions in OpenSSL or GNU
crypt instead of the SHA2 implementation bundled with sudo.
* Fixed a compilation error on systems without the stdbool.h header
file. Bug #778.
* Fixed a compilation error in the standalone Kerberos V authentication
module. Bug #777.
* Added the iolog_flush flag to sudoers which causes I/O log data
to be written immediately to disk instead of being buffered.
* I/O log files are now created with group ID 0 by default unless
the "iolog_user" or "iolog_group" options are set in \
sudoers.
* It is now possible to store I/O log files on an NFS-mounted
file system where uid 0 is remapped to an unprivileged user.
The "iolog_user" option must be set to a non-root user and the
top-level I/O log directory must exist and be owned by that user.
* Added the restricted_env_file setting to sudoers which is similar
to env_file but its contents are subject to the same restrictions
as variables in the invoking user's environment.
* Fixed a use after free bug in the SSSD backend when the fqdn
sudoOption is enabled and no hostname value is present in
/etc/sssd/sssd.conf.
* Fixed a typo that resulted in a compilation error on systems
where the killpg() function is not found by configure.
* Fixed a compilation error with the included version of zlib
when sudo was built outside the source tree.
* Fixed the exit value of sudo when the command is terminated by
a signal other than SIGINT. This was broken in sudo 1.8.15 by
the fix for Bug #722. Bug #784.
* Fixed a regression introduced in sudo 1.8.18 where the "lecture"
option could not be used in a positive boolean context, only
a negative one.
* Fixed an issue where sudo would consume stdin if it was not
connected to a tty even if log_input is not enabled in sudoers.
Bug #786.
* Clarify in the sudoers manual that the #includedir directive
diverts control to the files in the specified directory and,
when parsing of those files is complete, returns control to the
original file. Bug #775.
What's new in Sudo 1.8.19p2
* Fixed a crash in visudo introduced in sudo 1.8.9 when an IP address
or network is used in a host-based Defaults entry. Bug #766
* Added a missing check for the ignore_iolog_errors flag when
the sudoers plugin generates the I/O log file path name.
* Fixed a typo in sudo's vsyslog() replacement that resulted in
garbage being logged to syslog.
What's new in Sudo 1.8.19p1
* Fixed a bug introduced in sudo 1.8.19 that resulted in the wrong
syslog priority and facility being used.
What's new in Sudo 1.8.19
* New "syslog_maxlen" Defaults option to control the maximum size of
syslog messages generated by sudo.
* Sudo has been run against PVS-Studio and any issues that were
not false positives have been addressed.
* I/O log files are now created with the same group ID as the
parent directory and not the invoking user's group ID.
* I/O log permissions and ownership are now configurable via the
"iolog_mode", "iolog_user" and "iolog_group" \
sudoers Defaults
variables.
* Fixed configuration of the sudoers I/O log plugin debug subsystem.
Previously, I/O log information was not being written to the
sudoers debug log.
* Fixed a bug in visudo that broke editing of files in an include
dir that have a syntax error. Normally, visudo does not edit
those files, but if a syntax error is detected in one, the user
should get a chance to fix it.
* Warnings about unknown or unparsable sudoers Defaults entries now
include the file and line number of the problem.
* Visudo will now use the file and line number information about an
unknown or unparsable Defaults entry to go directly to the file
with the problem.
* Fixed a bug in the sudoers LDAP back-end where a negated sudoHost
entry would prevent other sudoHost entries following it from matching.
* Warnings from visudo about a cycle in an Alias entry now include the
file and line number of the problem.
* In strict mode, visudo will now use the file and line number
information about a cycle in an Alias entry to go directly to the
file with the problem.
* The sudo_noexec.so file is now linked with -ldl on systems that
require it for the wordexp() wrapper.
* Fixed linking of sudo_noexec.so on macOS systems where it must be
a dynamic library and not a module.
* Sudo's "make check" now includes a test for sudo_noexec.so
working.
* The sudo front-end now passes the user's umask to the plugin.
Previously the plugin had to determine this itself.
* Sudoreplay can now display the stdin and ttyin streams when they
are explicitly added to the filter list.
* Fixed a bug introduced in sudo 1.8.17 where the "all" setting
for verifypw and listpw was not being honored. Bug #762.
* The syslog priority (syslog_goodpri and syslog_badpri) can now
be negated or set to "none" to disable logging of successful or
unsuccessful sudo attempts via syslog.
What's new in Sudo 1.8.18p1
* When sudo_noexec.so is used, the WRDE_NOCMD flag is now added
if the wordexp() function is called. This prevents commands
from being run via wordexp() without disabling it entirely.
* On Linux systems, sudo_noexec.so now uses a seccomp filter to
disable execute access if the kernel supports seccomp. This is
more robust than the traditional method of using stub functions
that return an error.
What's new in Sudo 1.8.18
* The sudoers locale is now set before parsing the sudoers file.
If sudoers_locale is set in sudoers, it is applied before
evaluating other Defaults entries. Previously, sudoers_locale
was used when evaluating sudoers but not during the inital parse.
Bug #748.
* A missing or otherwise invalid #includedir is now ignored instead
of causing a parse error.
* During "make install", backup files are only used on HP-UX where
it is not possible to unlink a shared object that is in use.
This works around a bug in ldconfig on Linux which could create
links to the backup shared library file instead of the current
one.
* Fixed a bug introduced in 1.8.17 where sudoers entries with long
commands lines could be truncated, preventing a match. Bug #752.
* The fqdn, runas_default and sudoers_locale Defaults settings are
now applied before any other Defaults settings since they can
change how other Defaults settings are parsed.
* On systems without the O_NOFOLLOW open(2) flag, when the NOFOLLOW
flag is set, sudoedit now checks whether the file is a symbolic link
before opening it as well as after the open. Bug #753.
* Sudo will now only resolve a user's group IDs to group names
when sudoers includes group-based permissions. Group lookups
can be expensive on some systems where the group database is
not local.
* If the file system holding the sudo log file is full, allow
the command to run unless the new ignore_logfile_errors Defaults
option is disabled. Bug #751.
* The ignore_audit_errors and ignore_iolog_errors Defaults options
have been added to control sudo's behavior when it is unable to
write to the audit and I/O logs.
* Fixed a bug introduced in 1.8.17 where the SIGPIPE signal handler
was not being restored when sudo directly executes the command.
* Fixed a bug where "sudo -l command" would indicate that a command
was runnable even when denied by sudoers when using the LDAP or
SSSD backends.
* The match_group_by_gid Defaults option has been added to allow
sites where group name resolution is slow and where sudoers only
contains a small number of groups to match groups by group ID
instead of by group name.
* Fixed a bug on Linux where a 32-bit sudo binary could fail with
an "unable to allocate memory" error when run on a 64-bit system.
Bug #755
* When parsing ldap.conf, sudo will now only treat a '#' character
as the start of a comment when it is at the beginning of the
line.
* Fixed a potential crash when auditing is enabled and the audit
function fails with an error. Bug #756
* Norwegian Nynorsk translation for sudo from translationproject.org.
* Fixed a typo that broke short host name matching when the fqdn
flag is enabled in sudoers. Bug #757
* Negated sudoHost attributes are now supported by the LDAP and
SSSD backends.
* Fixed matching entries in the LDAP and SSSD backends when a
RunAsGroup is specified but no RunAsUser is present.
* Fixed "sudo -l" output in the LDAP and SSSD backends when a
RunAsGroup is specified but no RunAsUser is present.

Log message:
sudo: include the full regen of configure script.
I tried to exclude a hunk that seemed new, but that is probably wrong.
It didn't cause problems on my end at first, but does fail for others.
