The remote host is missing an update to linux
announced via advisory USN-1080-1.
Details follow:
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)
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)
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)
Krishna Gudipati discovered that the bfa adapter driver did not correctly
initialize certain structures. A local attacker could read files in /sys to
crash the system, leading to a denial of service. (CVE-2010-4343)
Tavis Ormandy discovered that the install_special_mapping function could
bypass the mmap_min_addr restriction. A local attacker could exploit this
to mmap 4096 bytes below the mmap_min_addr area, possibly improving the
chances of performing NULL pointer dereference attacks. (CVE-2010-4346)
It was discovered that the ICMP stack did not correctly handle certain
unreachable messages. If a remote attacker were able to acquire a socket
lock, they could send specially crafted traffic that would crash the
system, leading to a denial of service. (CVE-2010-4526)
Dan Rosenberg discovered that the OSS subsystem did not handle name
termination correctly. A local attacker could exploit this crash the system
or gain root privileges. (CVE-2010-4527)
Dan Carpenter discovered that the Infiniband driver did not correctly
handle certain requests. A local user could exploit this to crash the
system or potentially gain root privileges. (CVE-2010-4649, CVE-2011-1044)
Solution:
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 10.04 LTS:
linux-image-2.6.32-29-386 2.6.32-29.58
linux-image-2.6.32-29-generic 2.6.32-29.58
linux-image-2.6.32-29-generic-pae 2.6.32-29.58
linux-image-2.6.32-29-ia64 2.6.32-29.58
linux-image-2.6.32-29-lpia 2.6.32-29.58
linux-image-2.6.32-29-powerpc 2.6.32-29.58
linux-image-2.6.32-29-powerpc-smp 2.6.32-29.58
linux-image-2.6.32-29-powerpc64-smp 2.6.32-29.58
linux-image-2.6.32-29-preempt 2.6.32-29.58
linux-image-2.6.32-29-server 2.6.32-29.58
linux-image-2.6.32-29-sparc64 2.6.32-29.58
linux-image-2.6.32-29-sparc64-smp 2.6.32-29.58
linux-image-2.6.32-29-versatile 2.6.32-29.58
linux-image-2.6.32-29-virtual 2.6.32-29.58
After a standard system update you need to reboot your computer to make
all the necessary changes.
