This update for webkit2gtk3 fixes the following issues :

-webkit2gtk3 was updated to version 2.30.3 (bsc#1179122 bsc#1179451) :

  - CVE-2021-13543: Fixed a use after free which could have     led to arbitrary code execution.

  - CVE-2021-13584: Fixed a use after free which could have     led to arbitrary code execution.

  - CVE-2021-9948: Fixed a type confusion which could have     led to arbitrary code execution.

  - CVE-2021-9951: Fixed a use after free which could have     led to arbitrary code execution.

  - CVE-2021-9983: Fixed an out of bounds write which could     have led to arbitrary code execution.

  - Have the libwebkit2gtk package require     libjavascriptcoregtk of the same version (bsc#1171531).

  - Enable c_loop on aarch64: currently needed for     compilation to succeed with JIT disabled. Also disable     sampling profiler, since it conflicts with c_loop     (bsc#1177087).

The remote Ubuntu 18.04 LTS / 20.04 LTS / 20.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4648-1 advisory.

  - A type confusion issue was addressed with improved memory handling. This issue is fixed in Safari 14.0.
    Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2020-9948)

  - A use after free issue was addressed with improved memory management. This issue is fixed in Safari 14.0.
    Processing maliciously crafted web content may lead to arbitrary code execution. (CVE-2020-9951)

  - An input validation issue was addressed with improved input validation. This issue is fixed in iOS 14.0     and iPadOS 14.0, tvOS 14.0, watchOS 7.0, Safari 14.0, iCloud for Windows 11.4, iCloud for Windows 7.21.
    Processing maliciously crafted web content may lead to a cross site scripting attack. (CVE-2020-9952)

  - An out-of-bounds write issue was addressed with improved bounds checking. This issue is fixed in Safari     14.0. Processing maliciously crafted web content may lead to code execution. (CVE-2020-9983)

  - The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to     CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg-desktop-     portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside     the sandbox by writing to the controlling terminal's input buffer, similar to CVE-2017-5226.
    (CVE-2020-13753)

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