"The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:0205 advisory.

    Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

    CVE-2014-1745:
    Use-after-free vulnerability in the SVG implementation in Blink, as used in Google Chrome before
    35.0.1916.114, allows remote attackers to cause a denial of service or possibly have unspecified other
    impact via vectors that trigger removal of an SVGFontFaceElement object, related to
    core/svg/SVGFontFaceElement.cpp.

    CVE-2023-32359:
    A flaw was found in webkitgtk where a users password may be read aloud by a text-to-speech
    accessibility feature.

    CVE-2023-39928:
    A use-after-free vulnerability exists in the MediaRecorder API of Webkit WebKitGTK 2.40.5. A specially
    crafted web page can abuse this vulnerability to cause memory corruption and potentially arbitrary code
    execution. A user would need to to visit a malicious webpage to trigger this vulnerability.

    CVE-2023-40414:
    A use-after-free issue was addressed with improved memory management. This issue is fixed in watchOS 10,
    iOS 17 and iPadOS 17, tvOS 17, macOS Sonoma 14, Safari 17. Processing web content may lead to arbitrary
    code execution.

    CVE-2023-41983:
    The issue was addressed with improved memory handling. This issue is fixed in macOS Sonoma 14.1, Safari
    17.1, iOS 16.7.2 and iPadOS 16.7.2, iOS 17.1 and iPadOS 17.1. Processing web content may lead to a denial-
    of-service.

    CVE-2023-42852:
    A logic issue was addressed with improved checks. This issue is fixed in iOS 17.1 and iPadOS 17.1, watchOS
    10.1, iOS 16.7.2 and iPadOS 16.7.2, macOS Sonoma 14.1, Safari 17.1, tvOS 17.1. Processing web content may
    lead to arbitrary code execution.

    CVE-2023-42883:
    A flaw was found in WebKitGTK. This issue exists due to a boundary error when processing a malicious
    image, which could result in a denial of service.

    CVE-2023-42890:
    A flaw was found in WebKitGTK. This issue exists due to a boundary error when processing malicious HTML
    content in WebKit, which could result in memory corruption and arbitrary code execution on the target
    system.

    CVE-2024-23206:
    An access issue was addressed with improved access restrictions. This issue is fixed in watchOS 10.3, tvOS
    17.3, iOS 17.3 and iPadOS 17.3, macOS Sonoma 14.3, iOS 16.7.5 and iPadOS 16.7.5, Safari 17.3. A
    maliciously crafted webpage may be able to fingerprint the user.

    CVE-2024-23213:
    The issue was addressed with improved memory handling. This issue is fixed in watchOS 10.3, tvOS 17.3, iOS
    17.3 and iPadOS 17.3, macOS Sonoma 14.3, iOS 16.7.5 and iPadOS 16.7.5, Safari 17.3. Processing web content
    may lead to arbitrary code execution.
