USN-1394-1 : Linux kernel (OMAP4) vulnerabilities

Ubuntu Security Notice (C) 2012 Canonical, Inc. / NASL script (C) 2012 Tenable Network Security, Inc.


Synopsis :

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

Description :

Aristide Fattori and Roberto Paleari reported a flaw in the Linux
kernel's handling of IPv4 icmp packets. A remote user could exploit
this to cause a denial of service. (CVE-2011-1927)

Vegard Nossum discovered a leak in the kernel's inotify_init() system
call. A local, unprivileged user could exploit this to cause a denial
of service. (CVE-2010-4250)

An error was discovered in the kernel's handling of CUSE (Character
device in Userspace). A local attacker might exploit this flaw to
escalate privilege, if access to /dev/cuse has been modified to allow
non-root users. (CVE-2010-4650)

A flaw was found in the kernel's Integrity Measurement Architecture
(IMA). Changes made by an attacker might not be discovered by IMA, if
SELinux was disabled, and a new IMA rule was loaded. (CVE-2011-0006)

A flaw was found in the Linux Ethernet bridge's handling of IGMP
(Internet Group Management Protocol) packets. An unprivileged local
user could exploit this flaw to crash the system. (CVE-2011-0716)

Dan Rosenberg reported errors in the OSS (Open Sound System) MIDI
interface. A local attacker on non-x86 systems might be able to cause
a denial of service. (CVE-2011-1476)

Dan Rosenberg reported errors in the kernel's OSS (Open Sound System)
driver for Yamaha FM synthesizer chips. A local user can exploit this
to cause memory corruption, causing a denial of service or privilege
escalation. (CVE-2011-1477)

Dan Rosenberg reported an error in the old ABI compatibility layer of
ARM kernels. A local attacker could exploit this flaw to cause a
denial of service or gain root privileges. (CVE-2011-1759)

Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
partitions. A local user could exploit this to cause a denial of
service or escalate privileges. (CVE-2011-2182)

A flaw was discovered in the Linux kernel's AppArmor security
interface when invalid information was written to it. An unprivileged
local user could use this to cause a denial of service on the system.
(CVE-2011-3619)

It was discovered that some import kernel threads can be blocked by a
user level process. An unprivileged local user could exploit this
flaw to cause a denial of service. (CVE-2011-4621)

A flaw was discovered in the XFS filesystem. If a local user mounts a
specially crafted XFS image it could potential execute arbitrary code
on the system. (CVE-2012-0038)

Chen Haogang discovered an integer overflow that could result in
memory corruption. A local unprivileged user could use this to crash
the system. (CVE-2012-0044)
