Ubuntu Security Notice 1111-1 - Multiple vulnerabilities have been addressed in the Linux 2.6 kernel. Dan Rosenberg discovered multiple flaws in the X.25 facilities parsing. Vegard Nossum discovered that memory garbage collection was not handled correctly for active sockets. Nelson Elhage discovered that the kernel did not correctly handle process cleanup after triggering a recoverable kernel bug. Nelson Elhage discovered that Econet did not correctly handle AUN packets over UDP. Dan Rosenberg discovered that the OSS subsystem did not handle name termination correctly. Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. Dan Carpenter discovered that the TTPCI DVB driver did not check certain values during an ioctl. Jens Kuehnel discovered that the InfiniBand driver contained a race condition. Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values.

Ubuntu Security Notice USN-1111-1
May 05, 2011
linux-source-2.6.15 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 6.06 LTS
Summary:
Multiple flaws fixed in the Linux kernel.
Software Description:
- linux-source-2.6.15: Linux kernel
Details:
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)
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)
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)
Nelson Elhage discovered that Econet did not correctly handle AUN packets
over UDP. A local attacker could send specially crafted traffic to crash
the system, leading to a denial of service. (CVE-2010-4342)
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 Rosenberg discovered that IRDA did not correctly check the size of
buffers. On non-x86 systems, a local attacker could exploit this to read
kernel heap memory, leading to a loss of privacy. (CVE-2010-4529)
Dan Carpenter discovered that the TTPCI DVB driver did not check certain
values during an ioctl. If the dvb-ttpci module was loaded, a local
attacker could exploit this to crash the system, leading to a denial of
service, or possibly gain root privileges. (CVE-2011-0521)
Jens Kuehnel discovered that the InfiniBand driver contained a race
condition. On systems using InfiniBand, a local attacker could send
specially crafted requests to crash the system, leading to a denial of
service. (CVE-2011-0695)
Timo Warns discovered that the LDM disk partition handling code did not
correctly handle certain values. By inserting a specially crafted disk
device, a local attacker could exploit this to gain root privileges.
(CVE-2011-1017)
