high Nessus Plugin ID 76275

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-2257-1 advisory.

 Christof Schmitt discovered that Samba incorrectly initialized a certain response field when vfs shadow copy was enabled. A remote authenticated attacker could use this issue to possibly obtain sensitive information. This issue only affected Ubuntu 13.10 and Ubuntu 14.04 LTS. (CVE-2014-0178)

 It was discovered that the Samba internal DNS server incorrectly handled QR fields when processing incoming DNS messages. A remote attacker could use this issue to cause Samba to consume resources, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-0239)

 Daniel Berteaud discovered that the Samba NetBIOS name service daemon incorrectly handled certain malformed packets. A remote attacker could use this issue to cause Samba to consume resources, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and Ubuntu 14.04 LTS.
 (CVE-2014-0244)

 Simon Arlott discovered that Samba incorrectly handled certain unicode path names. A remote authenticated attacker could use this issue to cause Samba to stop responding, resulting in a denial of service.
 (CVE-2014-3493)

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.
