E.257.2. Changes
-
Remove security vulnerability that allowed connected
users to read backend memory (Tom)
The vulnerability involves changing the data type of a
table column used in a SQL function (CVE-2007-0555).
This error can easily be exploited to cause a backend
crash, and in principle might be used to read database
content that the user should not be able to access.
-
Fix rare bug wherein btree index page splits could fail
due to choosing an infeasible split point (Heikki
Linnakangas)
-
Tighten security of multi-byte character processing for
UTF8 sequences over three bytes long (Tom)
