## NISTリンク

<https://nvd.nist.gov/vuln/detail/CVE-2023-4863>

## 説明

116.0.5845.187より前のGoogle Chromeに含まれるWebPにヒープバッファオーバーフローの脆弱性があり、悪意のあるHTMLページを使うことで、リモートの攻撃者が範囲外へのメモリ書き込みを行えるおそれがあります (Chromiumのセキュリティ重要度: Critical)。

## Keeperへの影響

Keeper SecurityはElectronフレームワークを使用しているため、デスクトップアプリがこの脆弱性の影響を受けるおそれがあります。予防措置として、Electronフレームワークをただちにv22.3.24に更新し、[Keeper Desktop version 16.10.8](/release-notes/jp/desktop/web-vault-+-desktop-app/vault-release-16.10.8.md)を公開しました。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.keeper.io/release-notes/jp/keeper-security/security-advisories/cve-2023-4863.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
