samba - several vulnerabilities

Several vulnerabilities have been discovered in Samba, a SMB/CIFS file,
print, and login server. The Common Vulnerabilities and Exposures project
identifies the following problems:

• CVE-2009-1886
  The smbclient utility contains a formatstring vulnerability where
  commands dealing with file names treat user input as format strings
  to asprintf.
• CVE-2009-1888
  In the smbd daemon, if a user is trying to modify an access control
  list (ACL) and is denied permission, this deny may be overridden if
  the parameter “dos filemode” is set to “yes” in the smb.conf and the
  user already has write access to the file.

The old stable distribution (etch) is not affected by these problems.

For the stable distribution (lenny), these problems have been fixed in
version 3.2.5-4lenny6.

The unstable distribution (sid), which is only affected by CVE-2009-1888,
will be fixed soon.

We recommend that you upgrade your samba package.
