What would be your proposed naming scheme?

OK I stand corrected, but my proposal is the same, because it still informs 
people, that this is not something to worry about.

Can I suggest we name files, that contain virus especially (like CVE-* and 
VIRUS-*) so that it is obvious that the file contains a "wanted" virus.

none of these files actually contains a virus, they just have malformed
content that tend to trigger anti-virus heuristics.

it looks like the hang-*.tiff and hang-*.wmf are not encrypted.

the CVE-* files in the same directory are all encrypted with some dummy
password, so that virus scanners don't complain about them.

vcl/qa/cppunit/graphicfilter/data/README

i've taken the liberty to encrypt these now on master with
18b0343010517daa1eaf52a17ef19564076e1f3a, so you should only get virus
warnings when the tests are actually running (because the files will be
written unencrypted to temporary files), which can be avoided with
--disable-cve-tests.

virus detection with GData

2015-12-28 Thread Regina Henschel

Hi all,

I get a virus detection from scanner GData on the files
crash-1.tiff and hang-7.tiff in filter\qa\cppunit\data\tiff\fail, both 
Exploit.CVE-2015-5097-Gen


and a suspected virus on the file hang-3.wmf in 
vcl\qa\cppunit\graphicfilter\data\wmf\fail\ with Exploit.Win32.MS04-032.Gen


Kind regards
Regina

you can safely ignore these reports. Our */qa directories contain a number
of files that are detected by various virus scanners. The files are there
to prevent regressions with security issues.

If you want to know why they were added you can easily have a look with
something like git log -- filter/qa/cppunit/data/tiff/fail/hang-7.tiff
which would show you that Caolan has added that file to check for a problem
with some types of files. I think most of the new crash* and hang* files
have been added as a result of the AFL testing.

Markus
