samba - several vulnerabilities

Two local vulnerabilities have been discovered in samba, a SMB/CIFS file,
print, and login server for Unix. The Common Vulnerabilities and
Exposures project identifies the following problems:

• CVE-2009-3297
  Ronald Volgers discovered that a race condition in mount.cifs
  allows local users to mount remote filesystems over arbitrary
  mount points.
• CVE-2010-0547
  Jeff Layton discovered that missing input sanitising in mount.cifs
  allows denial of service by corrupting /etc/mtab.

For the stable distribution (lenny), these problems have been fixed in
version 2:3.2.5-4lenny9.

For the unstable distribution (sid), these problems have been fixed in
version 2:3.4.5~dfsg-2.

We recommend that you upgrade your samba packages.
