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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2025-36855/ (Markdown: https://insights.sbomify.com/CVE-2025-36855/index.md)","id":"CVE-2025-36855","markdown":"https://insights.sbomify.com/CVE-2025-36855/index.md","name":"CVE-2025-36855","record":{"aliases":["BIT-dotnet-2025-36855","BIT-dotnet-sdk-2025-36855","GHSA-642h-ggvv-j2c4"],"analysis":null,"analysis_generated_by":null,"assigner":"HeroDevs","cpe":[],"cvss":{"score":8.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-126","name":"Buffer Over-read"}],"description":"A vulnerability ( CVE-2025-21176 https://www.cve.org/CVERecord ) exists in DiaSymReader.dll due to buffer over-read.\n\n Per  CWE-126: Buffer Over-read https://cwe.mitre.org/data/definitions/126.html , Buffer Over-read is when a product reads from a buffer using buffer access mechanisms such as indexes or pointers that reference memory locations after the targeted buffer.\n\n  This issue affects EOL ASP.NET 6.0.0 \u003c= 6.0.36 as represented in this CVE, as well as 8.0.0 \u003c= 8.0.11 \u0026 \u003c= 9.0.0 as represented in CVE-2025-21176.\n\n \n\n Additionally, if you've deployed  self-contained applications https://docs.microsoft.com/dotnet/core/deploying/#self-contained-deployments-scd  targeting any of the impacted versions, these applications are also vulnerable and must be recompiled and redeployed.\n\n NOTE: This CVE affects only End Of Life (EOL) software components.
