"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
privacy. (CVE-2010-4075, CVE-2010-4077)

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 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)

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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
