The following updates has been released for Debian GNU/Linux:

Debian GNU/Linux 7 Extended LTS:
ELA-104-1 samba security update
ELA-105-1 sqlalchemy security update

Debian GNU/Linux 8 LTS:

ELA-104-1 samba security update

Package: samba
Version: 2:3.6.6-6+deb7u19
Related CVE: CVE-2019-3880
A flaw was found in the way Samba implemented an RPC endpoint emulating the Windows registry service API. An unprivileged attacker could have used this flaw to create a new registry hive file anywhere they had unix permissions which could have lead to creation of a new file in the Samba share.

For Debian 7 Wheezy, these problems have been fixed in version 2:3.6.6-6+deb7u19.

We recommend that you upgrade your samba packages.

DLA 1754-1: samba security update

Package : samba
Version : 2:4.2.14+dfsg-0+deb8u12
CVE ID : CVE-2017-9461 CVE-2018-1050 CVE-2018-1057 CVE-2019-3880


Various vulnerabilities were discovered in Samba, SMB/CIFS file, print,
and login server/client for Unix

CVE-2017-9461

smbd in Samba had a denial of service vulnerability (fd_open_atomic
infinite loop with high CPU usage and memory consumption) due to
wrongly handling dangling symlinks.

CVE-2018-1050

Samba was vulnerable to a denial of service attack when the RPC
spoolss service was configured to be run as an external daemon.
Missing input sanitization checks on some of the input parameters to
spoolss RPC calls could have caused the print spooler service to
crash.

CVE-2018-1057

On a Samba 4 AD DC the LDAP server of Samba incorrectly validated
permissions to modify passwords over LDAP allowing authenticated
users to change any other users' passwords, including administrative
users and privileged service accounts (eg Domain Controllers).

Thanks to the Ubuntu security team for having backported the rather
invasive changeset to Samba in Ubuntu 14.04 (which we could use to
patch Samba in Debian jessie LTS).

CVE-2019-3880

A flaw was found in the way Samba implemented an RPC endpoint
emulating the Windows registry service API. An unprivileged attacker
could have used this flaw to create a new registry hive file anywhere
they had unix permissions which could have lead to creation of a new
file in the Samba share.

For Debian 8 "Jessie", these problems have been fixed in version
2:4.2.14+dfsg-0+deb8u12.

We recommend that you upgrade your samba packages.
