| Description: | Summary:
The remote host is missing an update for the 'linux, linux-ec2' package(s) announced via the USN-1089-1 advisory.
Vulnerability Insight:
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-2010-4076, 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)
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)
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)
