The remote Ubuntu host is missing one or more security-related
Timo Warns discovered that the EFI GUID partition table was not
correctly parsed. A physically local attacker that could insert
mountable devices could exploit this to crash the system or possibly
gain root privileges. (CVE-2011-1776)
Dan Rosenberg discovered that the IPv4 diagnostic routines did not
correctly validate certain requests. A local attacker could exploit
this to consume CPU resources, leading to a denial of service.
Dan Rosenberg discovered that the Bluetooth stack incorrectly handled
certain L2CAP requests. If a system was using Bluetooth, a remote
attacker could send specially crafted traffic to crash the system or
gain root privileges. (CVE-2011-2497)
Fernando Gont discovered that the IPv6 stack used predictable fragment
identification numbers. A remote attacker could exploit this to
exhaust network resources, leading to a denial of service.
Time Warns discovered that long symlinks were incorrectly handled on
Be filesystems. A local attacker could exploit this with a malformed
Be filesystem and crash the system, leading to a denial of service.
Darren Lavender discovered that the CIFS client incorrectly handled
certain large values. A remote attacker with a malicious server could
exploit this to crash the system or possibly execute arbitrary code as
the root user. (CVE-2011-3191).
