                     CVE-2025-43368

    The following vulnerabilities have been discovered in the WebKitGTK
    web engine:

    CVE-2025-43272

        Big Bear discovered that processing maliciously crafted web
        content may lead to an unexpected process crash.

    CVE-2025-43342

        An anonymous researcher discovered that processing maliciously
        crafted web content may lead to an unexpected process crash.

    CVE-2025-43343

        An anonymous researcher discovered that processing maliciously
        crafted web content may lead to an unexpected process crash.

    CVE-2025-43356

        Jaydev Ahire discovered that a website may be able to access
        sensor information without user consent.

    CVE-2025-43368

        Pawel Wylecial discovered that processing maliciously crafted web
        content may lead to an unexpected process crash.

    This WebKitGTK update causes a compatibility problem with older
    versions of Evolution when handling e-mail attachments. For this
    reason, fixed versions of Evolution have also been released along with
    this WebKitGTK update.

    For Debian 11 bullseye, these problems have been fixed in version
    2.50.1-1~deb11u1.

    We recommend that you upgrade your webkit2gtk packages.

    For the detailed security status of webkit2gtk please refer to
    its security tracker page at:
