See $URL.

Guess this deserves some attention, but writeable shares are needed:

CVE-2010-0926 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0926):
  The default configuration of smbd in Samba before 3.3.11, 3.4.x
  before 3.4.6, and 3.5.x before 3.5.0rc3, when a writable share
  exists, allows remote authenticated users to leverage a directory
  traversal vulnerability, and access arbitrary files, by using the
  symlink command in smbclient to create a symlink containing .. (dot
  dot) sequences, related to the combination of the unix extensions and
  wide links options.

Vulnerable versions are no longer in the tree.

GLSA Vote: no.

But may still exist installed on many systems.

Hi, Krzysztof.

Good point, and that is something to be considered when the team decides whether or not to publish a GLSA. At the same time, having fixed versions in the tree and stable allows us to jump ahead in the security process.

Vote: YES.

It's old so GLSA Vote: no -> Closing. Feel free to reopen if you disagree.
