Package: release.debian.org Severity: normal User: release.debian....@packages.debian.org Usertags: unblock X-Debbugs-Cc: openvswi...@packages.debian.org Control: affects -1 + src:openvswitch
Please unblock package openvswitch [ Reason ] The latest upload fixes CVE-2023-1668, that is: "Remote traffic denial of service via crafted packets with IP proto 0." [ Impact ] An attacker cloud fool OVS into inserting wrong taffic flow table entries that would wrongly redirect traffic, effectively leading to a DoS. [ Tests ] Upstream has a full unit test suite, and the patch includes new tests for this CVE. [ Risks ] The patch itself isn't that big, and I've checked that OVS continues to work. [ Checklist ] [x] all changes are documented in the d/changelog [x] I reviewed all changes and I approve them [x] attach debdiff against the package in testing unblock openvswitch/3.1.0-2

However, this is incorrect behavior as + relevant standards permit that any value, including '0' should be treated + as a valid value. + . + Because of this overload, when the ofproto layer builds action list for + a packet with nw_proto of 0, it won't build the complete action list that + we expect to be built for the packet. That will cause a bad behavior + where all packets passing the datapath will fall into an incomplete + action set. + . + The fix here is to unwildcard nw_proto, allowing us to preserve setting + actions for protocols which we know have support for the actions we + program. This means that a traffic which contains nw_proto == 0 cannot + cause connectivity breakage with other traffic on the link. +Author: Aaron Conole <acon...@redhat.com> +Date: Fri, 31 Mar 2023 17:17:27
