CVE-2019-25076 (https://sites.google.com/view/tuple-space-explosion): https://dl.acm.org/citation.cfm?doid=3359989.3365431 https://arxiv.org/abs/2011.09107 https://www.youtube.com/watch?v=DSC3m-Bww64 https://www.youtube.com/watch?v=5cHpzVK0D28 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. Fixed version isn't apparent to me
According to the vulnerability text, this only affects up to 2.17.2; and the oldest in the tree is now 2.17.8
(In reply to Robin Johnson from comment #1) > According to the vulnerability text, this only affects up to 2.17.2; and the > oldest in the tree is now 2.17.8 The vulnerable versions were in the tree earlier, so we still need to decide on issuing a GLSA for it.
