I'll play advocate of the devil then. Imagine a wiki running on a webserver,

that allows anybody to create new topics which end up in
/articles/[Topic].txt
with sufficient .htaccess stuff in /articles to twart most usual attacks ..


If you could create an arbitrary long topic, then you *might*
be able to execute some code, when some cronjob would scan the drive
and come across the file?

creating files is a different privilege than  running code. Hence imho
it's not a bogus advisory.


another possibility would be to create an archive that extracts an
incredibly
long filename perhaps? scanning an archive before/after it's extracted
is a pretty common event i guess.
