The remote SUSE host is missing one or more security updates.

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).

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.
