Package        : samba
Debian Bug     : 858564 858590 858648 859101

Two regressions were introduced by the samba update in DSA-3816-1.
Updated packages are now available to address these problems.
Additionally a regression from DSA-3548-1 causing `net ads join` to
freeze when run a second time is fixed along with this update. For
reference, the original advisory text follows.

Jann Horn of Google discovered a time-of-check, time-of-use race
condition in Samba, a SMB/CIFS file, print, and login server for Unix. A
malicious client can take advantage of this flaw by exploiting a symlink
race to access areas of the server file system not exported under a
share definition.

For the stable distribution (jessie), these problems have been fixed in
version 2:4.2.14+dfsg-0+deb8u5.

We recommend that you upgrade your samba packages.
