Possible Log exhaustion bug?
Summary: Possible Log exhaustion bug?
Product: Apache httpd-1.3
Version: 1.3.23
Platform: All
OS/Version: All
Status: UNCONFIRMED
Severity: Minor
Priority: Other
Component: Other

Greetings. I am not quite sure if you should classify this as a bug, but I
thought it would be interesting to pass it along. On all redhat systems and many
others I had a look at, the standard installation of Apache logs the full path
to a file that produces a 404 file not found or 414 Request URI-Too Large.
I was experimenting witht he following command:
wget `perl -e 'print "host"; print "A"x######; print "/";'`
While doing this I simply tailed the access log of the server I used to test
this on. I tried numbers between 6000 and 64000. I did not bother to try larger
numbers due to the limitations of wget. However I noticed, that access_log wrote
all of the xxxx thousand "A" I put into the request into the logfile.
Even when the request URI was obviously too large all of the xxx chars in the
path are logged.
This creates a possible space exhaustion on the partition apache logs upon. If I
can write more than 64000 chars per request into the logfile it should be farily
easy to cram the logfile. Also I noticed a slight delay while apache is writing
the 64000 chars to the logfile.
Is this a valid concern? Thank you.
