CVE-2006-1269: "Buffer overflow in the parse function in parse.c in zoo
2.10 might allow local users to execute arbitrary code via long filename
command line arguments, which are not properly handled during archive
creation.  NOTE: since this issue is local and not setuid, the set of
attack scenarios is limited, although is reasonable to expect that there
are some situations in which the zoo user might automatically list
attacker-controlled filenames to add to the zoo archive."

- From https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=183426:

  Here is how to reproduce this issue:

  mkdir `perl -e 'print "A"x254'`
  cd `perl -e 'print "A"x254'`
  mkdir `perl -e 'print "A"x254'`
  cd `perl -e 'print "A"x254'`
  touch feh
  cd ../..
  zoo a arch.zoo `perl -e 'print "A"x254 . "/" . "A"x254 . "/feh"'`

I have confirmed that Debian's zoo_2.10-17 is vulnerable and do not see
that this issue has been fixed for sarge/woody.  A dpatch for the fix
(created from instructions in the Red Hat bugzilla entry) is included.
After building with the patch, the test case no longer causes zoo to
segfault.
