Releases

• Ubuntu 15.10
• Ubuntu 15.04
• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• ldb - LDAP-like embedded database

Details

Thilo Uttendorfer discovered that the ldb incorrectly handled certain zero
values. A remote attacker could use this issue to cause applications using
ldb, such as Samba, to stop responding, resulting in a denial of service.
(CVE-2015-3223)

Douglas Bagnall discovered that ldb incorrectly handled certain string
lengths. A remote attacker could use this issue to possibly access
sensitive information from memory of applications using ldb, such as Samba.
(CVE-2015-5330)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 15.10

• libldb1 - 2:1.1.20-2ubuntu0.1

Ubuntu 15.04

• libldb1 - 1:1.1.18-1ubuntu0.1

Ubuntu 14.04

• libldb1 - 1:1.1.16-1ubuntu0.1

Ubuntu 12.04

After a standard system update you need to restart applications using ldb,
such as Samba, to make all the necessary changes.
