ldb vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.10
- Ubuntu 15.04
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in ldb.
Software Description:
- 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 LTS:
libldb1 1:1.1.16-1ubuntu0.1
Ubuntu 12.04 LTS:
libldb1 1:1.1.4-1ubuntu0.1
After a standard system update you need to restart applications using ldb,
such as Samba, to make all the necessary changes.
