            Bug ID: 196552
           Summary: Make HSTS list handling more robust against unexpected
                    content
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

Crash tracing data indicates that the network process is sometimes handed malformed HSTS data, leading to a nullptr dereference. This patch adds some assertions to catch the invalid state in debug builds, and allows the process to ignore the bad data and continue.
