Description Wouter de Jong 2007-03-12 14:25:43 UTC

MySQL Announce List email :

This release also resolves a crashing bug that could be exploited as a
potential local Denial of Service attack,

We would like to thank Stefan Streichsbier from SEC Consult, who also
informed us about this bug via our mail address - he
will send out a separate advisory about his findings.

Could mysql be updated to 5.0.37 anytime soon, or at least have the patches 
backported ? There are more bugs fixed, fe. :

* Some CASE statements inside stored routines could lead to excessive resource 
usage or a crash of the server. (Bug#24854, Bug#19194) 
* Some joins in which one of the joined tables was a view could return 
erroneous results or crash the server. (Bug#24345) 

Many thanks :)

The MySQL folk don't seem to think that 5.0.37 is a security release, and I
don't plan to treat it as one.  I've built it in rawhide and will consider
pushing it into FC6 if there are not too many squawks; but the list of
incompatibilities seems a bit worrisome.

Hi! What incompatabilities are you referring to?

Comment 3 Tom Lane 2007-03-13 04:51:18 UTC
Read the release notes for yourself ... the one that sticks in my mind at 12:50AM local time is a potential 
forced dump-and-reload for enum columns.  There were a few others that seemed a bit questionable for 
an allegedly stable release branch.
