Description:

   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).
