Description Lubomir Kundrak 2006-10-26 15:01:11 UTC 
Description of problem:

The three crash conditions are not considered critical vulnerabilities, because
all three require authenticated access to the database with the ability to run
ad-hoc queries, and none can be exploited for privilege escalation.

1.) Disallow aggregate functions in UPDATE commands, except within sub-SELECTs (Tom)
(The behavior of such an aggregate was unpredictable, and in 8.1.X could cause a
crash, so it has been disabled. The SQL standard does not allow this either.)

2.) Fix core dump when an untyped literal is taken as ANYARRAY

3.) Fix core dump in duration logging for extended query protocol when a COMMIT
or ROLLBACK is executed

Version-Release number of selected component (if applicable):

1.) >=7.4.1, Affects RHEL 4.1, FC5, FC6
2.) >=8.1, Affects FC5, FC6
3.) >=8.1, Affects FC5, FC6
