Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
It was discovered that the stack guard page for processes in the Linux
kernel was not sufficiently large enough to prevent overlapping with
the heap. An attacker could leverage this with another vulnerability
to execute arbitrary code and gain administrative privileges
Roee Hay discovered that the parallel port printer driver in the Linux
kernel did not properly bounds check passed arguments. A local
attacker with write access to the kernel command line arguments could
use this to execute arbitrary code. (CVE-2017-1000363)
A double free bug was discovered in the IPv4 stack of the Linux
kernel. An attacker could use this to cause a denial of service
(system crash). (CVE-2017-8890)
Andrey Konovalov discovered an IPv6 out-of-bounds read error in the
Linux kernel's IPv6 stack. A local attacker could cause a denial of
service or potentially other unspecified problems. (CVE-2017-9074)
Andrey Konovalov discovered a flaw in the handling of inheritance in
the Linux kernel's IPv6 stack. A local user could exploit this issue
to cause a denial of service or possibly other unspecified problems.
It was discovered that dccp v6 in the Linux kernel mishandled
inheritance. A local attacker could exploit this issue to cause a
denial of service or potentially other unspecified problems.
It was discovered that the transmission control protocol (tcp) v6 in
the Linux kernel mishandled inheritance. A local attacker could
exploit this issue to cause a denial of service or potentially other
unspecified problems. (CVE-2017-9077)
Jann Horn discovered that bpf in Linux kernel does not restrict the
output of the print_bpf_insn function. A local attacker could use this
to obtain sensitive address information. (CVE-2017-9150)
It was discovered that the IPv6 stack was doing over write consistency
check after the data was actually overwritten. A local attacker could
exploit this flaw to cause a denial of service (system crash).
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.
Update the affected packages.
