Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS

Summary:

Samba could be made to create files in unexpected locations.

Software Description: - samba: SMB/CIFS file, print, and login server for Unix

Details:

Ubuntu 18.10:
libsmbclient 2:4.8.4+dfsg-2ubuntu2.3
samba 2:4.8.4+dfsg-2ubuntu2.3

Ubuntu 18.04 LTS:
libsmbclient 2:4.7.6+dfsg~ubuntu-0ubuntu2.9
samba 2:4.7.6+dfsg~ubuntu-0ubuntu2.9

Ubuntu 16.04 LTS:
libsmbclient 2:4.3.11+dfsg-0ubuntu0.16.04.19
samba 2:4.3.11+dfsg-0ubuntu0.16.04.19

libsmbclient 2:4.3.11+dfsg-0ubuntu0.14.04.20
samba 2:4.3.11+dfsg-0ubuntu0.14.04.20
