A information disclosure vulnerability exists when TLS components use weak hash algorithms. An attacker who successfully exploited this vulnerability could obtain information to further compromise a users's encrypted transmission channel.
To exploit the vulnerability, an attacker would have to conduct a man-in-the-middle attack.
The update addresses the vulnerability by correcting how TLS components use hash algorithms.

What it is: CVE-2020-1596 is a medium-severity vulnerability in Microsoft Windows 10, published on 11 Sep 2020. It can only be exploited from the same machine or local network, with no action from the victim. Exploitation: There is no known exploitation of CVE-2020-1596 in the wild and no public exploit code. Affected product: Microsoft Windows 10. No package-level version data is available, so check the vendor advisory linked from the reference page. Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
