Comment 0 for bug 1668017

I'm running a web application serving rather big binary blobs from a MariaDB table. After the unattended update (7.0.8-0ubuntu0.16.04.3 to 7.0.15-0ubuntu0.16.04.2), the application would routinely break while trying to fetch a >16Mbyte row from the database server.

Requests resulting in a row under 16Mbyte are processed normally, anything above it would return columns in the wrong order, and right around 0xFFFFF2 a null-character (0x00) is inserted into the stream (when the resulting file is compared to one served with the version used previously)

Rolling back to 7.0.4-7ubuntu2 immediately fixed the issue. I'm pretty sure the problem was introduced somewhere between 7.0.8 and 7.0.15, but I cant find anything relevant in the changelog for those versions.

Please let me know what I can do to assist!
