Ubuntu 14.04 LTS : linux vulnerabilities (USN-2544-1)

Ubuntu Security Notice (C) 2015-2016 Canonical, Inc. / NASL script (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

Eric Windisch discovered flaw in how the Linux kernel's XFS file
system replaces remote attributes. A local access with access to an
XFS file system could exploit this flaw to escalate their privileges.
(CVE-2015-0274)

A flaw was discovered in the automatic loading of modules in the
crypto subsystem of the Linux kernel. A local user could exploit this
flaw to load installed kernel modules, increasing the attack surface
and potentially using this to gain administrative privileges.
(CVE-2013-7421)

The Linux kernel's splice system call did not correctly validate its
parameters. A local, unprivileged user could exploit this flaw to
cause a denial of service (system crash). (CVE-2014-7822)

A flaw was discovered in the crypto subsystem when screening module
names for automatic module loading if the name contained a valid
crypto module name, eg. vfat(aes). A local user could exploit this
flaw to load installed kernel modules, increasing the attack surface
and potentially using this to gain administrative privileges.
(CVE-2014-9644).

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 linux-image-3.13-generic,
linux-image-3.13-generic-lpae and / or linux-image-3.13-lowlatency
packages.

Risk factor :

High / CVSS Base Score : 7.2
(CVSS2#AV:L/AC:L/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 5.3
(CVSS2#E:U/RL:OF/RC:C)
