Subject: Re: CVE id request: libc fortify source information
disclosure
I think this technically qualifies as an "exposure" which is the "E" in
"CVE" - it can be used as a stepping stone for exploitation of another
vulnerability. (Very old, unwieldy definitions here:
http://cve.mitre.org/about/terminology.html)
The risk may be very minimal, but the FORTIFY_SOURCE protection mechanism
is not working "as advertised" - it can be manipulated for an
admittedly-small information leak.
Use CVE-2010-3192 for the issue.
