Ubuntu Security Notice (C) 2011-2016 Canonical, Inc. / NASL script (C) 2011-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
Dan Rosenberg discovered that multiple terminal ioctls did not
correctly initialize structure memory. A local attacker could exploit
this to read portions of kernel stack memory, leading to a loss of
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
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 that the SCSI subsystem did not correctly
validate iov segments. A local attacker with access to a SCSI device
could send specially crafted requests to crash the system, leading to
a denial of service. (CVE-2010-4163, CVE-2010-4668)
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.
Alan Cox discovered that the HCI UART driver did not correctly check
if a write operation was available. If the mmap_min-addr sysctl was
changed from the Ubuntu default to a value of 0, a local attacker
could exploit this flaw to gain root privileges. (CVE-2010-4242)
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.
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.
Update the affected packages.
