The third beta version of sudo 1.8.15 is now available.

In addition to bug fixes, sudo 1.8.15 includes changes to how the
time stamp files are locked which could use some more extensive
testing.  The upshot is that sudo can now be used multiple times
in a pipeline even when a password is required and the user will
only be prompted once.

Major changes between sudo 1.8.15b3 and 1.8.15b2:

 * Fixed a potential double free introduced in 1.8.15b1 when sudo
   is suspended at the password prompt.

Major changes between sudo 1.8.15b2 and 1.8.15b1:

 * Fixed a bug introduced in sudo 1.8.14 that prevented visudo from
   re-editing the correct file when a syntax error was detected.

 * Fixed a bug where sudo would not relay a SIGHUP signal to the
   command when the terminal is closed and the command is not run
   in its own pseudo-tty.  Bug #719

Major changes between sudo 1.8.15b1 and 1.8.14p3:

 * Fixed a bug that prevented sudo from building outside the source tree
   on some platforms.  Bug #708.

 * Fixed the location of the sssd library in the RHEL/Centos packages.
   Bug #710.

 * Fixed a build problem on systems that don't implicitly include
   sys/types.h from other header files.  Bug #711.

 * Fixed a problem on Linux using containers where sudo would ignore
   signals sent by a process in a different container.

 * Sudo now refuses to run a command if the PAM session module
   returns an error.

 * When editing files with sudoedit, symbolic links will no longer
   be followed by default.  The old behavior can be restored by
   enabling the sudoedit_follow option in sudoers or on a per-command
   basis with the FOLLOW and NOFOLLOW tags.  Bug #707.

 * Fixed a bug introduced in version 1.8.14 that caused the last
   valid editor in the sudoers "editor" list to be used by visudo
   and sudoedit instead of the first.  Bug #714.

 * Fixed a bug in visudo that prevented the addition of a final
   newline to edited files without one.

 * Fixed a bug decoding certain base64 digests in sudoers when the
   intermediate format included a '=' character.

 * Individual records are now locked in the time stamp file instead
   of the entire file.  This allows sudo to avoid prompting for a
   password multiple times on the same terminal when used in a
   pipeline.  In other words, "sudo cat foo | sudo grep bar" now
   only prompts for the password once.  Previously, both sudo
   processes would prompt for a password, often making it impossible
   to enter.

 * Fixed a bug where sudo would fail to run commands as a non-root
   user on systems that lack both setresuid() and setreuid().
   Bug #713.
Version: GnuPG v1
