Which leads to the upstream commit at:
It seems that this issue is not specific to chromium-browser, but affects versions of sqlite shipped with Red Hat Enterprise Linux and Fedora.
This flaw basically causes sqlite to leak the underlying memory location, when some operations are performed. This memory-address leak can be used by other (more severe) flaws to potentially result in code-execution.
The patch adds new API functions, "sqlite3_bind_pointer(), sqlite3_result_pointer(), and sqlite3_value_pointer() used to safely move pointer values through SQL without exposing underlying memory address information."
This patch is included in the sqlite-3.20.0 release.
More details about the new API (interfaces) and how they can be used is available at:
