New! Plugin Severity Now Using CVSS v3

Synopsis

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

Description

The SUSE Linux Enterprise Server 12 kernel was updated to 3.12.39 to receive various security and bugfixes.

Following security bugs were fixed :

- CVE-2015-0777: The XEN usb backend could leak information to the guest system due to copying uninitialized memory.

- CVE-2015-2150: Xen and the Linux kernel did not properly restrict access to PCI command registers, which might have allowed local guest users to cause a denial of service (non-maskable interrupt and host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing the device, which triggers an Unsupported Request (UR) response.

The update package also includes non-security fixes. See advisory for details.

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