CVE-2020-35498 Denial of service attacks, in which crafted network packets could cause the packet lookup to ignore network header fields from layers 3 and 4. The crafted network packet is an ordinary IPv4 or IPv6 packet with Ethernet padding length above 255 bytes. This causes the packet sanity check to abort parsing header fields after layer 2. CVE-2020-27827 Denial of service attacks using crafted LLDP packets. CVE-2018-17206 Buffer over-read issue during BUNDLE action decoding. CVE-2018-17204 Assertion failure due to not validating information (group type and command) in OF1.5 decoder. CVE-2017-9214 Buffer over-read that is caused by an unsigned integer underflow. CVE-2015-8011 Buffer overflow in the lldp_decode function in daemon/protocols/lldp.c in lldpd before 0.8.0 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries. For Debian 9 stretch, these problems have been fixed in version 2.6.10-0+deb9u1. This version is a new upstream point release. We recommend that you upgrade your openvswitch packages.
