exclude list problems (PEBKAC?)

[pointer]

I've checked the docs/FAQ/google/archives and I must be missing
something really simple. :\

I have an amanda client that I'm backing having problems backing up.

We're using tar for /usr on this client:

SNIP disklist snippet
client /usr no-mirror-tar
SNIP

Here's the def for no-mirror-tar:

SNIP amanda.conf snippet
define dumptype no-mirror-tar {
global
program GNUTAR
compress client fast
comment usr partitions dumped with tar
exclude list .amanda-exclude.gtar
priority medium
}
SNIP

The global config only has a comment and 'index yes.'

The exclude list (on the client) has this:

SNIP
$ cat /usr/.amanda-exclude.gtar
./local/mirror
./local/www/logs
SNIP



The runtar.debug looks like this:

SNIP
gtar: version 2.4.2
running: /usr/local/bin/tar: gtar --create --directory /usr
--listed-incremental /usr/local/var/amanda/gnutar-lists/client_usr_0.new
--sparse --one-file-system --ignore-failed-read --totals --file -
--exclude-from /usr/.amanda-exclude.gtar .
SNIP

And the backup of this partition errors out with this:

SNIP
/-- client  /usr lev 0 FAILED [/usr/local/bin/tar returned 2]
sendbackup: start [client:/usr level 0]
sendbackup: info BACKUP=/usr/local/bin/tar
sendbackup: info RECOVER_CMD=/usr/local/bin/gzip -dc |/usr/local/bin/tar
-f... -
sendbackup: info COMPRESS_SUFFIX=.gz
sendbackup: info end
? gtar: Cannot add file ./local/mirror/pub/redhat/i386
.
.
.
| Total bytes written: 8484853760
? gtar: Error exit delayed from previous errors
sendbackup: error [/usr/local/bin/tar returned 2]
\
SNIP

There's also a 'file changed as we read it' error, but all of these
errors come from ./local (/usr/local) in places that are excluded (see
above).

Suggestions?

Thanks,

Mike

 Your config looks correct to me.
 What does '/usr/local/bin/tar --version' show?

SNIP
$ /usr/local/bin/tar  --version
tar (GNU tar) 1.13

 Can your backup user read the exclude file?

Yes.

SNIP
$ ls -al /usr/.amanda-exclude.gtar
-rw-r--r--   1 root other  32 Oct 10 10:22
/usr/.amanda-exclude.gtar
SNIP

Thanks for the heads-up.  I'd seen this, but hadn't gotten around to
updating it.  Yes, bad, bad, bad!  Anyone know when a new version is
coming out to fix CAN-2002-0399?

Did I misunderstand the vuln announcement, or is this really only
exploitable when a superuser extracts files from a tarball without
looking at the contents...?
