medium Nessus Plugin ID 83761

Language:

Synopsis

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

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2615-1 advisory.

 Alexandre Oliva reported a race condition flaw in the btrfs file system's handling of extended attributes (xattrs). A local attacker could exploit this flaw to bypass ACLs and potentially escalate privileges.
 (CVE-2014-9710)

 A memory corruption issue was discovered in AES decryption when using the Intel AES-NI accelerated code path. A remote attacker could exploit this flaw to cause a denial of service (system crash) or potentially escalate privileges on Intel base machines with AEC-GCM mode IPSec security association. (CVE-2015-3331)

 A flaw was discovered in the Linux kernel's IPv4 networking when using TCP fast open to initiate a connection. An unprivileged local user could exploit this flaw to cause a denial of service (system crash). (CVE-2015-3332)

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.

Solution
