openvswitch: MPLS buffer overflow vulnerability

A buffer overflow flaw was discovered in the OVS processing of MPLS labels. A remote attacker able to deliver a frame containing a malicious MPLS label that would be processed by OVS could trigger the flaw and use the resulting memory corruption to cause a denial of service DoS or, possibly,...

UBUNTU-CVE-2016-2074

Buffer overflow in lib/flow.c in ovs-vswitchd in Open vSwitch 2.2.x and 2.3.x before 2.3.3 and 2.4.x before 2.4.1 allows remote attackers to execute arbitrary code via crafted MPLS packets, as demonstrated by a long string in an ovs-appctl command...

I/O port access privilege escalation in x86-64 Linux

ISSUE DESCRIPTION IRET and POPF do not modify EFLAGS.IOPL when executed by code at a privilege level other than zero. Since PV Xen guests run at privilege level 3 for 64-bit ones; 32-bit ones run at privilege level 1, to compensate for this the context switching of EFLAGS.IOPL requires the guest ...

Voice over LTE implementations contain multiple vulnerabilities

Overview Long Term Evolution LTE mobile networks are currently deployed through the world. These LTE mobile networks make use of full packet switching and the IP protocol, unlike previous iterations of the mobile network. This change from circuit switching to packet switching allows new attacks n...

Windows Drivers are True’ly Tricky

Posted by James Forshaw, Driving for Bugs Auditing a product for security vulnerabilities can be a difficult challenge, and there’s no guarantee you’ll catch all vulnerabilities even when you do. This post describes an issue I identified in the Windows Driver code for Truecrypt, which has already...

Cisco IOS XE Network Address Translation and Multiprotocol Label Switching DoS (CSCut96933)

The remote Cisco IOS XE device is missing vendor-supplied security patches, and is configured for Network Address Translation NAT and/or Multiprotocol Label Switching MPLS. It is, therefore, affected by a flaw in the NAT and MPLS services due to improper processing of IPv4 packets. An...
