coreutils-8.2 released [stable]

[Jim Meyering]

This is to announce coreutils-8.2.
This is a bug-fix-only "stable" release.

Not only does this release fix a few bugs in the tools, but it fixes two
exploitable bugs in the build rules.  One (the "make dist" vulnerability)
was fixed by regenerating all Makefile.in files using a fixed version
of automake[1].  That bug affects all package using automake-generated
Makefile.in files.  The other vulnerability (the "make distcheck" bug
mentioned below) is specific to this package.  You would be vulnerable
only if you were to run "make distcheck" on a system with a local attacker.

As usual, this release includes a ton of gnulib improvements
(104 change-sets worth).  Thanks to everyone who has been helping.

Here are the GPG detached signatures[*]:

  http://ftp.gnu.org/gnu/coreutils/coreutils-8.2.tar.xz.sig

[*] You can use either of the above signature files to verify that
the corresponding file (without the .sig suffix) is intact.  First,
be sure to download both the .sig file and the corresponding tarball.
Then, run a command like this:

  gpg --verify coreutils-8.2.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys B9AB9A16

and rerun the `gpg --verify' command.

This release was bootstrapped with the following tools:

NEWS

* Noteworthy changes in release 8.2 (2009-12-11) [stable]

** Bug fixes

  id's use of mgetgroups no longer writes beyond the end of a malloc'd buffer
  [bug introduced in coreutils-8.1]

  id no longer crashes on systems without supplementary group support.
  [bug introduced in coreutils-8.1]

  rm once again handles zero-length arguments properly.
  The rewrite to make rm use fts introduced a regression whereby
  a command like "rm a '' b" would fail to remove "a" and "b", due to
  the presence of the empty string argument.
  [bug introduced in coreutils-8.0]

  sort is now immune to the signal handling of its parent.
  Specifically sort now doesn't exit with an error message
  if it uses helper processes for compression and its parent
  ignores CHLD signals. [bug introduced in coreutils-6.9]

  tail without -f no longer access uninitialized memory
  [bug introduced in coreutils-7.6]

  timeout is now immune to the signal handling of its parent.
  Specifically timeout now doesn't exit with an error message
  if its parent ignores CHLD signals. [bug introduced in coreutils-7.6]

  a user running "make distcheck" in the coreutils source directory,
  with TMPDIR unset or set to the name of a world-writable directory,
  and with a malicious user on the same system
  was vulnerable to arbitrary code execution
  [bug introduced in coreutils-5.0]
