CVE-2015-7540  (opens in a new tab)
CWE-399  (opens in a new tab)

How to fix?

Upgrade Ubuntu:16.04 samba to version 2:4.3.3+dfsg-1ubuntu1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream samba package and not the samba package as distributed by Ubuntu. See How to fix? for Ubuntu:16.04 relevant fixed versions and status.

The LDAP server in the AD domain controller in Samba 4.x before 4.1.22 does not check return values to ensure successful ASN.1 memory allocation, which allows remote attackers to cause a denial of service (memory consumption and daemon crash) via crafted packets.
