CVE-2019-8375 (opens in a new tab)Amendment
The SLES security team deemed this advisory irrelevant for SLES:15.0.
NVD Description
Note: Versions mentioned in the description apply only to the upstream webkit-jsc-4 package and not the webkit-jsc-4 package as distributed by SLES.
The UIProcess subsystem in WebKit, as used in WebKitGTK through 2.23.90 and WebKitGTK+ through 2.22.6 and other products, does not prevent the script dialog size from exceeding the web view size, which allows remote attackers to cause a denial of service (Buffer Overflow) or possibly have unspecified other impact, related to UIProcess/API/gtk/WebKitScriptDialogGtk.cpp, UIProcess/API/gtk/WebKitScriptDialogImpl.cpp, and UIProcess/API/gtk/WebKitWebViewGtk.cpp, as demonstrated by GNOME Web (aka Epiphany).
