I'm guessing this urgent email mentions SQL Anywhere because of TDS, but it contains no further information related to SQL Anywhere... so, what's the story here? Does it have to do with this, from a recent SQL Anywhere EBF readme? ================(Build #3519 - Engineering Case #692216)================
A problem with TDS secure logins has been corrected.
Here is the email... from: css_ucn@sybase.com

I believe the equivalent fix for SQL Anywhere is CR #692216, fixed in SQL Anywhere versions 11.0.1.2724 and 12.0.1.3519, and up. Please see our EBF Website to download the EBF patch: http://downloads.sybase.com/swd/summary.do?baseprod=144&client=ianywhere&timeframe=0 Probably a silly question, but does that mean it doesn't effect v10 ?

Not a silly question. The answer is yes, the issue does affect v10 and earlier SA versions (that supported TDS) but since these versions are EOL'ed there are no updates for them.

Thanks Breck.

Not even for a security vulnerability that was fixed a month before v10 went end of life, that's pretty poor isn't it ?

To clarify, if we don't use OpenClient or jConnect, then we don't have to apply the EBF, right?

Correct. The issue only affected TDS connections.
(25 Jul '12, 11:24)
Mark Culp
I thought TDS was enabled by default and you had to use TDS=NO to disable it, but I'm sure someone will clarify that.
(25 Jul '12, 11:24)
Daz Liquid
Yes, this is correct that TDS connections are accepted by default - if you use TCP/IP communications but do not support jConnect or Open Client connections, you can ensure that you are not affected by this issue by using http://dcx.sybase.com/index.html#1201/en/dbadmin/tds-conparm.html However, the issue affects TDS secure logins specifically, so if you do not have any TDS connections making logins, you will also not be exposed to this bug and yes, you would not have to apply the EBF for this use-case.

So just to be clear, the only way we'll ever be able to secure v10 databases is to never use jConnect or Open client after stopping them all and adding that to the start-up ?
(25 Jul '12, 11:33)
Daz Liquid
It does look that way from the docs, so in the words of Dr. Venkman, "OK. Important safety tip." We'll advise our customers to add TDS=NO to the tcpip parameters in their server startup command.

I second that question, and also ask that one: What exactly is a "TDS secure login", and can I use a TDS connection without a secure login? - If the latter is true (and also the default - which I guess), then for these connections no (additional) security problem has been noticed, and why should one worry then? AFAIK, a secure login would require the use of jConnect's ENCRYPT_PASSWORD connection property - but I'm not
