Details

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 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)

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 kvm did not correctly clear memory. A local
attacker could exploit this to read portions of the kernel stack, leading
to a loss of privacy. (CVE-2010-3881)

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 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 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)

Dan Rosenberg discovered that the socket filters did not correctly
initialize structure memory. A local attacker could create malicious
filters to read portions of kernel stack memory, leading to a loss of
privacy. (CVE-2010-4158)

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)

Dan Rosenberg discovered that certain iovec operations did not calculate
page counts correctly. A local attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-4162)

Dan Rosenberg discovered multiple flaws in the X.25 facilities parsing. If
a system was using X.25, a remote attacker could exploit this to crash the
system, leading to a denial of service. (CVE-2010-4164)

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)

Dan Rosenberg discovered that the RDS protocol did not correctly check
ioctl arguments. A local attacker could exploit this to crash the system,
leading to a denial of service. (CVE-2010-4175)

Brad Spengler discovered that the kernel did not correctly account for
userspace memory allocations during exec() calls. A local attacker could
exploit this to consume all system memory, leading to a denial of service.
(CVE-2010-4243)

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)

It was discovered that named pipes did not correctly handle certain fcntl
calls. A local attacker could exploit this to crash the system, leading to
a denial of service. (CVE-2010-4256)

Nelson Elhage discovered that the kernel did not correctly handle process
cleanup after triggering a recoverable kernel bug. If a local attacker were
able to trigger certain kinds of kernel bugs, they could create a specially
crafted process to gain root privileges. (CVE-2010-4258)

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 10.10
Ubuntu 10.04

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
