远程主机受到 GLSA-202104-03 中所述漏洞的影响（WebkitGTK+：多个漏洞）

    已在 WebkitGTK+ 中发现多个漏洞。请检查下方引用的 CVE 标识符以了解详细信息。
  影响：

    攻击者通过诱骗用户访问恶意构建的 Web 内容，或可执行任意代码，违反 iframe 沙盒策略，访问任意服务器上的受限端口，造成内存损坏，或可能造成拒绝服务情况。
  变通方案：

    目前无任何已知的变通方案。

远程主机上正在运行的 macOS / Mac OS X 版本为低于 10.14.6 安全更新 2021-001 Mojave 的 10.14.x、低于 10.15.7 安全更新 2021-001 的 10.15.x，或低于 11.2 的 11.x。因此，该应用程序受到多个漏洞的影响，其中包括：

  - 存在一个逻辑问题，可导致内存损坏。已通过改进状态管理解决此问题。
    应用程序可能以内核权限执行任意代码。(CVE-2020-27904)

  - 存在一个逻辑问题，允许应用程序以内核权限执行任意代码。
    (CVE-2021-1750)

  - 由不当输入验证导致的越界写入问题，允许恶意构建的 USD 文件意外终止应用程序或造成任意代码执行。(CVE-2021-1762)

请注意，Nessus 并未测试此问题，而是只依靠操作系统自我报告的版本号来判断。

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - 已通过改进限制解决逻辑问题。此问题已在 macOS Big Sur 11.2、安全更新 2021-001 Catalina、安全更新 2021-001 Mojave、iOS 14.4 和 iPadOS 14.4 中修复。远程攻击者或可造成任意代码执行。Apple 从报告中获悉，此问题可能已经被主动利用。(CVE-2021-1870)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

The remote NewStart CGSL host, running version MAIN 6.02, has webkit2gtk3 packages installed that are affected by multiple vulnerabilities:

  - A use-after-free issue was found in the AudioSourceProviderGStreamer class of WebKitGTK and WPE WebKit in     versions prior to 2.30.5. Processing maliciously crafted web content may lead to arbitrary code execution.
    The highest threat from this vulnerability is to data confidentiality and integrity as well as system     availability. (CVE-2020-13558)

  - A use-after-free issue was found in WebKitGTK and WPE WebKit in versions prior to 2.30.6. Processing     maliciously crafted web content may lead to arbitrary code execution. The highest threat from this     vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-27918)

  - A flaw was found in WebKitGTK and WPE WebKit in versions prior to 2.30.6. A user may be unable to fully     delete the browsing history under some circumstances. The highest threat from this vulnerability is to     data confidentiality. (CVE-2020-29623)

  - A flaw was found in WebKitGTK and WPE WebKit in versions prior to 2.30.6. Maliciously crafted web content     may violate the iframe sandboxing policy. The highest threat from this vulnerability is to data integrity.
    (CVE-2021-1765, CVE-2021-1801)

  - A use-after-free issue was found in WebKitGTK and WPE WebKit in versions prior to 2.32.0. Processing     maliciously crafted web content may lead to arbitrary code execution. The highest threat from this     vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-1788)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote host is running a version of macOS / Mac OS X that is 10.14.x prior to 10.14.6 Security Update 2021-001 Mojave, 10.15.x prior to 10.15.7 Security Update 2021-001 Catalina, or 11.x prior to 11.2. It is, therefore, affected by multiple vulnerabilities, including the following:

  - A logic issue existed resulting in memory corruption. This was addressed with improved state management.
    An application may be able to execute arbitrary code with kernel privileges. (CVE-2020-27904)

  - A logic issue existed that allowed applications to execute arbitrary code with kernel privileges.
    (CVE-2021-1750)

  - An out-of-bounds-write caused by improper input validation allowed maliciously crafted USD files to     unexpectedly terminate an application or cause arbitrary code execution. (CVE-2021-1762)

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

The remote host is affected by the vulnerability described in GLSA-202104-03 (WebkitGTK+: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in WebkitGTK+. Please       review the CVE identifiers referenced below for details.
  Impact :

    An attacker, by enticing a user to visit maliciously crafted web       content, may be able to execute arbitrary code, violate iframe sandboxing       policy, access restricted ports on arbitrary servers, cause memory       corruption, or could cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A logic issue was addressed with improved restrictions. This issue is fixed in macOS Big Sur 11.2,     Security Update 2021-001 Catalina, Security Update 2021-001 Mojave, iOS 14.4 and iPadOS 14.4. A remote     attacker may be able to cause arbitrary code execution. Apple is aware of a report that this issue may     have been actively exploited.. (CVE-2021-1870)

Note that Nessus relies on the presence of the package as reported by the vendor.
