USN-2855-1 fixed vulnerabilities in Samba. The upstream fix for
CVE-2015-5252 introduced a regression in certain specific environments.
This update fixes the problem.
Original advisory details:
Thilo Uttendorfer discovered that the Samba LDAP server incorrectly handled
certain packets. A remote attacker could use this issue to cause the LDAP
server to stop responding, resulting in a denial of service. This issue
only affected Ubuntu 14.04 LTS, Ubuntu 15.04 and Ubuntu 15.10.
(CVE-2015-3223)
Jan Kasprzak discovered that Samba incorrectly handled certain symlinks. A
remote attacker could use this issue to access files outside the exported
share path. (CVE-2015-5252)
Stefan Metzmacher discovered that Samba did not enforce signing when
creating encrypted connections. If a remote attacker were able to perform a
machine-in-the-middle attack, this flaw could be exploited to view sensitive
information. (CVE-2015-5296)
It was discovered that Samba incorrectly performed access control when
using the VFS shadow_copy2 module. A remote attacker could use this issue
to access snapshots, contrary to intended permissions. (CVE-2015-5299)
Douglas Bagnall discovered that Samba incorrectly handled certain string
lengths. A remote attacker could use this issue to possibly access
sensitive information. (CVE-2015-5330)
It was discovered that the Samba LDAP server incorrectly handled certain
packets. A remote attacker could use this issue to cause the LDAP server to
stop responding, resulting in a denial of service. This issue only affected
Ubuntu 14.04 LTS, Ubuntu 15.04 and Ubuntu 15.10. (CVE-2015-7540)
Andrew Bartlett discovered that Samba incorrectly checked administrative
privileges during creation of machine accounts. A remote attacker could
possibly use this issue to bypass intended access restrictions in certain
environments. This issue only affected Ubuntu 14.04 LTS, Ubuntu 15.04 and
Ubuntu 15.10. (CVE-2015-8467)
