action needed

The VCS repository is not up to date, push the missing commits. high

vcswatch reports that the current version of the package is not in its VCS.
Either you need to push your commits and/or your tags, or the information about the package's VCS are out of date. A common cause of the latter issue when using the Git VCS is not specifying the correct branch when the packaging is not in the default one (remote HEAD branch), which is usually "master" but can be modified in salsa.debian.org in the project's general settings with the "Default Branch" field). Alternatively the Vcs-Git field in debian/control can contain a "-b <branch-name>" suffix to indicate what branch is used for the Debian packaging.

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.
