    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.
