Fedora 39 : openvswitch (2024-a4530e9bfe)

medium Nessus Plugin ID 192171

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 39 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2024-a4530e9bfe advisory.

 - 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. (CVE-2023-3966)

 - 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. (CVE-2023-5366)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected openvswitch package.
