high Nessus Plugin ID 87756

Language:

Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected libldb1 package.
