In OpenVSX version v0.9.0 to v0.20.0, the /user/namespace/{namespace}/details API allows a user to edit all namespace details, even if the user is not a namespace Owner or Contributor. The details include: name, description, website, support link and social media links. The same issues existed in /user/namespace/{namespace}/details/logo and allowed a user to change the logo.

A flaw was found in Open vSwitch where multiple versions are vulnerable to crafted Geneve packets, which may result in a denial of service and invalid memory accesses. Triggering this issue requires that hardware offloading via the netlink path is enabled.

openvswitch 2.17.8 was discovered to contain a memory leak via the function xmalloc__ in openvswitch-2.17.8/lib/util.c.

A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses.

In NVS365 V01, the background network test function can trigger command execution.

NVS365 V01 is vulnerable to Incorrect Access Control. After entering a wrong password, the url will be sent to the server twice. In the second package, the server will return the correct password information.

An integer underflow in Organization Specific TLV was found in various versions of OpenvSwitch.

An out-of-bounds read in Organization Specific TLV was found in various versions of OpenvSwitch.

The TSS (Tuple Space Search) algorithm in Open vSwitch 2.x through 2.17.2 and 3.0.0 allows remote attackers to cause a denial of service (delays of legitimate traffic) via crafted packet data that requires excessive evaluation time within the packet classification algorithm for the MegaFlow cache, aka a Tuple Space Explosion (TSE) attack.

A flaw was found in dpdk. This flaw allows a malicious vhost-user master to attach an unexpected number of fds as ancillary data to VHOST_USER_GET_INFLIGHT_FD / VHOST_USER_SET_INFLIGHT_FD messages that are not closed by the vhost-user slave. By sending such messages continuously, the vhost-user master exhausts available fd in the vhost-user slave process, leading to a denial of service.
