high Nessus Plugin ID 87756

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2856-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
