"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).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
