3 security issues in trixie high

There are 3 open security issues in trixie.

1 important issue:

CVE-2026-36499: A missing upper-bound check in the udpif_set_threads() function of Open vSwitch v3.6.90 allows an attacker with OVSDB write access to request an excessive number of handler or revalidation threads. This can cause a denial of service (DoS) via resource exhaustion.

2 issues left for the package maintainer to handle:

CVE-2019-25076: (postponed; to be fixed through a stable update) 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.
CVE-2026-34956: (needs triaging) A flaw was found in Open vSwitch. When Open vSwitch is configured with a conntrack flow using FTP helpers over the userspace datapath, a remote attacker can send a specially crafted FTP stream with an EPASV command exceeding 255 characters. This heap access error can lead to a crash, resulting in a Denial of Service (DoS) for the affected system.

You can find information about how to handle these issues in the security team's documentation.

testing migrations

This package will soon be part of the auto-openssl transition. You might want to ensure that your package is ready for it. You can probably find supplementary information in the debian-release archives or in the corresponding release.debian.org bug.
excuses:
- Migration status for openvswitch (3.7.1-2 to 3.7.1-3): BLOCKED: Rejected/violates migration policy/introduces a regression
- Issues preventing migration:
- ∙ ∙ Reproducibility regression on arm64: openvswitch-common, openvswitch-ipsec, openvswitch-switch, openvswitch-switch-dpdk, openvswitch-testcontroller, openvswitch-vtep, python3-openvswitch
- Additional info (not blocking):
- ∙ ∙ Piuparts tested OK - https://piuparts.debian.org/sid/source/o/openvswitch.html
- ∙ ∙ Autopkgtest skipped on i386: not installable (which is allowed)
- ∙ ∙ Autopkgtest for openvswitch/3.7.1-3: amd64: Pass, arm64: Pass, loong64: Pass, ppc64el: Pass, riscv64: Pass, s390x: Pass
- ∙ ∙ Reproduced on amd64 - info
- ∙ ∙ Reproduced on armhf - info
- ∙ ∙ Reproduced on i386 - info
- ∙ ∙ Required age reduced by 3 days because of autopkgtest
- ∙ ∙ 3 days old (needed 2 days)
- Not considered
