    <Details xml:lang="en:us" source="Mitre">
ImageMagick before 7.1.2-22 contains an information disclosure vulnerability in the PasskeyEncipherImage method due to AES-CTR nonce reuse. Attackers can exploit nonce reuse in the cipher implementation to recover plaintext information from encrypted images.
    </Details>
    <Details xml:lang="en:us" source="Red Hat">
A vulnerability has been identified in ImageMagick, a software tool used to create, edit, and convert image files. This flaw allows a remote attacker to potentially decrypt and view images that were supposed to be securely encrypted by the software, leading to an unauthorized disclosure of sensitive data.
    </Details>
    <Statement xml:lang="en:us">
This Low impact information disclosure flaw in ImageMagick arises from AES-CTR nonce reuse within the `PasskeyEncipherImage` method. Exploitation requires an attacker to specifically target encrypted images processed by this method, which is not a common default configuration in Red Hat environments. The vulnerability primarily affects applications utilizing the `PasskeyEncipherImage` function, potentially through bindings like Magick.NET.
    </Statement>
    <Mitigation xml:lang="en:us">
To mitigate this stop using ImageMagick's built-in encryption feature. Rely on standard, OS-level data-at-rest encryption (such as LUKS) to protect sensitive media instead.
    </Mitigation>
