Ubuntu 9.10 : linux, linux-ec2 vulnerabilities (USN-1073-1)

Ubuntu Security Notice (C) 2011-2014 Canonical, Inc. / NASL script (C) 2011-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

Gleb Napatov discovered that KVM did not correctly check certain
privileged operations. A local attacker with access to a guest kernel
could exploit this to crash the host system, leading to a denial of
service. (CVE-2010-0435)

Dan Jacobson discovered that ThinkPad video output was not correctly
access controlled. A local attacker could exploit this to hang the
system, leading to a denial of service. (CVE-2010-3448)

It was discovered that KVM did not correctly initialize certain CPU
registers. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-3698)

Dan Rosenberg discovered that the Linux kernel TIPC implementation
contained multiple integer signedness errors. A local attacker could
exploit this to gain root privileges. (CVE-2010-3859)

Thomas Pollet discovered that the RDS network protocol did not check
certain iovec buffers. A local attacker could exploit this to crash
the system or possibly execute arbitrary code as the root user.
(CVE-2010-3865)

Dan Rosenberg discovered that the Linux kernel X.25 implementation
incorrectly parsed facilities. A remote attacker could exploit this to
crash the kernel, leading to a denial of service. (CVE-2010-3873)

Dan Rosenberg discovered that the CAN protocol on 64bit systems did
not correctly calculate the size of certain buffers. A local attacker
could exploit this to crash the system or possibly execute arbitrary
code as the root user. (CVE-2010-3874)

Vasiliy Kulikov discovered that the Linux kernel X.25 implementation
did not correctly clear kernel memory. A local attacker could exploit
this to read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3875)

Vasiliy Kulikov discovered that the Linux kernel sockets
implementation did not properly initialize certain structures. A local
attacker could exploit this to read kernel stack memory, leading to a
loss of privacy. (CVE-2010-3876)

Vasiliy Kulikov discovered that the TIPC interface did not correctly
initialize certain structures. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy.
(CVE-2010-3877)

Nelson Elhage discovered that the Linux kernel IPv4 implementation did
not properly audit certain bytecodes in netlink messages. A local
attacker could exploit this to cause the kernel to hang, leading to a
denial of service. (CVE-2010-3880)

Dan Rosenberg discovered that IPC structures were not correctly
initialized on 64bit systems. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4073)

Dan Rosenberg discovered that the USB subsystem did not correctly
initialize certian structures. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4074)

Dan Rosenberg discovered that the SiS video driver did not correctly
clear kernel memory. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4078)

Dan Rosenberg discovered that the ivtv V4L driver did not correctly
initialize certian structures. A local attacker could exploit this to
read kernel stack memory, leading to a loss of privacy.
(CVE-2010-4079)

Dan Rosenberg discovered that the RME Hammerfall DSP audio interface
driver did not correctly clear kernel memory. A local attacker could
exploit this to read kernel stack memory, leading to a loss of
privacy. (CVE-2010-4080, CVE-2010-4081)

Dan Rosenberg discovered that the VIA video driver did not correctly
clear kernel memory. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4082)

Dan Rosenberg discovered that the semctl syscall did not correctly
clear kernel memory. A local attacker could exploit this to read
kernel stack memory, leading to a loss of privacy. (CVE-2010-4083)

James Bottomley discovered that the ICP vortex storage array
controller driver did not validate certain sizes. A local attacker on
a 64bit system could exploit this to crash the kernel, leading to a
denial of service. (CVE-2010-4157)

Dan Rosenberg discovered that the Linux kernel L2TP implementation
contained multiple integer signedness errors. A local attacker could
exploit this to to crash the kernel, or possibly gain root privileges.
(CVE-2010-4160)

Steve Chen discovered that setsockopt did not correctly check MSS
values. A local attacker could make a specially crafted socket call to
crash the system, leading to a denial of service. (CVE-2010-4165)

Dave Jones discovered that the mprotect system call did not correctly
handle merged VMAs. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-4169)

It was discovered that multithreaded exec did not handle CPU timers
correctly. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-4248)

Vegard Nossum discovered that memory garbage collection was not
handled correctly for active sockets. A local attacker could exploit
this to allocate all available kernel memory, leading to a denial of
service. (CVE-2010-4249).

Solution :

Update the affected packages.
