This update for webkit2gtk3 to version 2.20.5 fixes the following issues :
Security issue fixed :
CVE-2018-12911: Fix off-by-one in xdg_mime_get_simple_globs (bsc#1101999).

A memory corruption issue was addressed with improved memory handling.
CVE-2018-4266: A malicious website may be able to cause a denial of service. A race condition was addressed with additional validation.
CVE-2018-4270, CVE-2018-4271, CVE-2018-4273: Processing maliciously crafted web content may lead to an unexpected application crash. A memory corruption issue was addressed with improved input validation.
CVE-2018-4278: A malicious website may exfiltrate audio data cross-origin. Sound fetched through audio elements may be exfiltrated cross-origin. This issue was addressed with improved audio taint tracking.
Other bugs fixed: Fix rendering artifacts in some websites due to a bug introduced in 2.20.4.
Fix a crash when leaving accelerated compositing mode.
Fix non-deterministic build failure due to missing JavaScriptCore/JSContextRef.h.
