The first three references to CVE-2008-4113[1] are incorrect. Please
update the CVE with the following references:

[1] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4113
This was in reference to the TKADV2008-007 advisory.

I guess the question becomes - TKADV2008-007 talks about separate issues,
one involving crashes by calling the API functions when SCTP-AUTH is
disabled (CVE-2008-3792), and another involving SCTP_HMAC_IDENT and a
length value for sctp_getsockopt_hmac_ident.

I see what the confusion is now.

TKADV2008-007[1] mentioned two separate, but related issues. The second
issue that the advisory mentioned is an example of a function that may
have two possible consequences, and it all depends on whether SCTP
authentication is enabled or not.

The patch[2] that addressed these issues mentioned only one of them in
the changelog description, even though it appears to be fixing possibly
more than two issues.

Should this be assigned with just one CVE name instead of two?

I re-read it over again, and I agree that assigning two CVE names for
this makes sense. Sorry for the confusion.

Thanks, Eugene
