Ubuntu Security Notice (C) 2014 Canonical, Inc. / NASL script (C) 2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Sasha Levin reported a flaw in the Linux kernel's point-to-point
protocol (PPP) when used with the Layer Two Tunneling Protocol (L2TP).
A local user could exploit this flaw to gain administrative
privileges. (CVE-2014-4943)

Salva Peiró discovered an information leak in the Linux kernel's
media- device driver. A local attacker could exploit this flaw to
obtain sensitive information from kernel memory. (CVE-2014-1739)

A bounds check error was discovered in the socket filter subsystem of
the Linux kernel. A local user could exploit this flaw to cause a
denial of service (system crash) via crafted BPF instructions.
(CVE-2014-3144)

A remainder calculation error was discovered in the socket filter
subsystem of the Linux kernel. A local user could exploit this flaw to
cause a denial of service (system crash) via crafted BPF instructions.
(CVE-2014-3145)

A flaw was discovered in the Linux kernel's handling of hugetlb
entries. A local user could exploit this flaw to cause a denial
service (memory corruption or system crash). (CVE-2014-3940)

Don Bailey discovered a flaw in the LZO decompress algorithm used by
the Linux kernel. An attacker could exploit this flaw to cause a
denial of service (memory corruption or OOPS). (CVE-2014-4608)

Don Bailey and Ludvig Strigeus discovered an integer overflow in the
Linux kernel's implementation of the LZ4 decompression algorithm, when
used by code not complying with API limitations. An attacker could
exploit this flaw to cause a denial of service (memory corruption) or
possibly other unspecified impact. (CVE-2014-4611).

Solution :

Update the affected linux-image-3.13.0-32-generic,
linux-image-3.13.0-32-generic-lpae and / or
linux-image-3.13.0-32-lowlatency packages.

Risk factor :

Medium / CVSS Base Score : 6.9
(CVSS2#AV:L/AC:M/Au:N/C:C/I:C/A:C)
CVSS Temporal Score : 6.0
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
