Description Josh Bressers 2011-08-24 15:00:50 UTC 
Apache HTTP Server allows remote attackers to obtain information via (1)
the ETag header, which reveals the inode number, or (2) multipart MIME
boundary, which reveals child proccess IDs (PID).
Comment 1 Josh Bressers 2011-08-24 15:03:39 UTC 
Statement:

Red Hat does not consider this to be a security issue. The information returned poses no threat to the target machine running httpd.
Comment 2 Tomas Hoger 2011-09-05 11:06:42 UTC 
Recent upstream discussion and upstream bug report:
http://thread.gmane.org/gmane.comp.apache.devel/45495
https://issues.apache.org/bugzilla/show_bug.cgi?id=49623

As pointed out there, content of the ETag header can be controlled using the FileETag directive.  Its default value is: INode MTime Size

Changing to MTime Size will cause httpd to not use file INode in the ETag headers.
