5 January 2016
Several security issues were fixed in ldb.
Releases
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
Ubuntu 15.04
Ubuntu 14.04
Ubuntu 12.04
After a standard system update you need to restart applications using ldb,
such as Samba, to make all the necessary changes.
