The remote openSUSE host is missing a security update.

Description

This update for webkit2gtk3 to version 2.20.3 fixes the following issues :

These security issues were fixed :

- CVE-2018-4190: An unspecified issue allowed remote attackers to obtain sensitive credential information that is transmitted during a CSS mask-image fetch (bsc#1097693).

- CVE-2018-4199: An unspecified issue allowed remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a crafted website (bsc#1097693)

- CVE-2018-4218: An unspecified issue allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted website that triggers an @generatorState use-after-free (bsc#1097693)

- CVE-2018-4222: An unspecified issue allowed remote attackers to execute arbitrary code via a crafted website that leverages a getWasmBufferFromValue out-of-bounds read during WebAssembly compilation (bsc#1097693)

- CVE-2018-4232: An unspecified issue allowed remote attackers to overwrite cookies via a crafted website (bsc#1097693)

- CVE-2018-4233: An unspecified issue allowed remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted website (bsc#1097693)

- CVE-2018-11646: webkitFaviconDatabaseSetIconForPageURL and webkitFaviconDatabaseSetIconURLForPageURL mishandle an unset pageURL, leading to an application crash (bsc#1095611).

These non-security issues were fixed :

- Disable Gigacage if mmap fails to allocate in Linux.

- Add user agent quirk for paypal website.

- Fix a network process crash when trying to get cookies of about:blank page.

- Fix UI process crash when closing the window under Wayland.

- Fix several crashes and rendering issues. This update was imported from the SUSE:SLE-15:Update update project.
