Comment 5 Huzaifa S. Sidhpurwala 2017-08-07 05:19:03 UTC
The chromium bug is private, but looking at the commit:

https://chromium.googlesource.com/chromium/src.git/+/3bfe67c9c4b45eb713326aae7a67c8f7390dae08

Which leads to the upstream commit at:

https://www.sqlite.org/src/info/d6a44b352d432d52

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:

https://www.sqlite.org/bindptr.html
