Ok, rewind to early 2017. My team was going to write a SPIR-V backend to DXC, lovingly called Spiregg github.com/microsoft/Dire….
Question was: how were we going to test it?

GDAL 2.3.0 released! Sadly, I didn't get to test the release candidates (newborn human in the house) @EvenRouault has been crazy productive and this... "More than 1000 fixes for issues/vulnerabilities found by OSS-Fuzz"

I am really proud of my team for receiving a best paper award at #esecfse19!
Check it out at ai.google/research/pubs/…. We synthesize drivers that find security and reliability issues using fuzzing. Many run in #ossfuzz - supported with integration rewards security.googleblog.com/2018/11/a-new-… pic.twitter.com/eQpF6rlCTz

#GDAL has so far been > 14% of the #OSSFuzz bugs. Measured by 675 commits crediting OSS Fuzz and OSS Fuzz being at about bug 4672. Credit to @EvenRouault for bug fixing!

#ossfuzz is now fuzzing GDAL on i386 and has already found a few 32-bit specific (or generic but easier to spot) bugs

#ossfuzz creativity makes me discover features of GDAL I was unaware of. For example "ogr2ogr myoutputdatasource myinputdatasourcewithseverallayers -nln somename" will 'merge' all the input layers into a single one (for drivers that support adding fields to non empty layers)

Ironically the #ossfuzz fuzzer for ogr2ogr I wrote to find bugs in the writing part of drivers also helps finding bugs in the reading part :-)

I'm crediting #OSSFuzz in ticket commits for bugs it discovered in ... fuzzers I wrote for it...

@kurtschwehr Discovering from Bas email that someone has taken care of registering a CVE at least for one of the GDAL #ossfuzz issues: nvd.nist.gov/vuln/detail/CV… . Why this one and not others is a mystery :-)

Crazy that this UK/Ordnance Survey NTF vector format, that no one no longer uses, generates so many #OSSFuzz bug reports.

Ok, first fix of a fuzzer bug is: github.com/google/effcee/…
When parsing the checks string, there are cases where a string intended as a regexp isn't a valid RE2 regexp.
The fix is to check those cases and fail early. Prevents a heap-buffer-overflow later on
