[ Christoph Berg ]
* New upstream security/bugfix release.
+ Shore up GRANT ... WITH ADMIN OPTION restrictions (Noah Misch)
Granting a role without ADMIN OPTION is supposed to prevent the grantee
from adding or removing members from the granted role, but this
restriction was easily bypassed by doing SET ROLE first. The security
impact is mostly that a role member can revoke the access of others,
contrary to the wishes of his grantor. Unapproved role member additions
are a lesser concern, since an uncooperative role member could provide
most of his rights to others anyway by creating views or SECURITY
DEFINER functions. (CVE-2014-0060)
+ Prevent privilege escalation via manual calls to PL validator functions
(Andres Freund)
The primary role of PL validator functions is to be called implicitly
during CREATE FUNCTION, but they are also normal SQL functions that a
user can call explicitly. Calling a validator on a function actually
written in some other language was not checked for and could be
exploited for privilege-escalation purposes. The fix involves adding a
call to a privilege-checking function in each validator function.
Non-core procedural languages will also need to make this change to
their own validator functions, if any. (CVE-2014-0061)
+ Avoid multiple name lookups during table and index DDL (Robert Haas,
Andres Freund)
If the name lookups come to different conclusions due to concurrent
activity, we might perform some parts of the DDL on a different table
than other parts. At least in the case of CREATE INDEX, this can be used
to cause the permissions checks to be performed against a different
table than the index creation, allowing for a privilege escalation
attack. (CVE-2014-0062)
+ Prevent buffer overrun with long datetime strings (Noah Misch)
The MAXDATELEN constant was too small for the longest possible value of
type interval, allowing a buffer overrun in interval_out(). Although the
datetime input functions were more careful about avoiding buffer
overrun, the limit was short enough to cause them to reject some valid
inputs, such as input containing a very long timezone name. The ecpg
library contained these vulnerabilities along with some of its own.
(CVE-2014-0063)
+ Prevent buffer overrun due to integer overflow in size calculations
(Noah Misch, Heikki Linnakangas)
Several functions, mostly type input functions, calculated an allocation
size without checking for overflow. If overflow did occur, a too-small
buffer would be allocated and then written past. (CVE-2014-0064)
+ Prevent overruns of fixed-size buffers (Peter Eisentraut, Jozef Mlich)
Use strlcpy() and related functions to provide a clear guarantee that
fixed-size buffers are not overrun. Unlike the preceding items, it is
unclear whether these cases really represent live issues, since in most
cases there appear to be previous constraints on the size of the input
string. Nonetheless it seems prudent to silence all Coverity warnings of
this type. (CVE-2014-0065)
+ Avoid crashing if crypt() returns NULL (Honza Horak, Bruce Momjian)
There are relatively few scenarios in which crypt() could return NULL,
but contrib/chkpass would crash if it did. One practical case in which
this could be an issue is if libc is configured to refuse to execute
unapproved hashing algorithms (e.g., "FIPS mode"). (CVE-2014-0066)
+ Document risks of make check in the regression testing instructions
(Noah Misch, Tom Lane)
Since the temporary server started by make check uses "trust"
authentication, another user on the same machine could connect to it as
database superuser, and then potentially exploit the privileges of the
operating-system user who started the tests. A future release will
probably incorporate changes in the testing procedure to prevent this
risk, but some public discussion is needed first. So for the moment,
just warn people against using make check when there are untrusted users
on the same machine. (CVE-2014-0067)
+ Rework tuple freezing protocol (Álvaro Herrera, Andres Freund)
The logic for tuple freezing was unable to handle some cases involving
freezing of multixact IDs, with the practical effect that shared
row-level locks might be forgotten once old enough.
Fixing this required changing the WAL record format for tuple freezing.
While this is no issue for standalone servers, when using replication it
means that standby servers must be upgraded to 9.3.3 or later before
their masters are. An older standby will be unable to interpret freeze
records generated by a newer master, and will fail with a PANIC message.
(In such a case, upgrading the standby should be sufficient to let it
resume execution.)
* The upstream tarballs no longer contain a plain HISTORY file, but point to
the html documentation. Note the location of these files in our
changelog.gz file.
* Teach configure to find tclsh8.6 where tclsh is not available.
[ Martin Pitt ]
* Build with LINUX_OOM_SCORE_ADJ=0 instead of the older LINUX_OOM_ADJ=0. All
relevant distro releases (>= squeeze/lucid) use kernels which support
/proc/pid/oom_score_adj, so avoid the dmesg warnings. (Closes: #646245,
LP: #991725)
* Bump Standards-Version to 3.9.5 (no changes necessary).
* Build with tcl8.6 where available (>= Jessie, >= trusty).

* Add 03-config-update.patch: Refresh config.{guess,sub} to latest version
for enabling ports, in particular the upcoming ppc64el.
[ Christoph Berg ]
* New upstream bugfix release.
+ Fix "VACUUM"'s tests to see whether it can update relfrozenxid
(Andres Freund)
In some cases "VACUUM" (either manual or autovacuum) could
incorrectly advance a table's relfrozenxid value, allowing tuples
to escape freezing, causing those rows to become invisible once
2^31 transactions have elapsed. The probability of data loss is
fairly low since multiple incorrect advancements would need to
happen before actual loss occurs, but it's not zero. In 9.2.0 and
later, the probability of loss is higher, and it's also possible to
get "could not access status of transaction" errors as a
consequence of this bug. Users upgrading from releases 9.0.4 or
8.4.8 or earlier are not affected, but all later versions contain
the bug.
The issue can be ameliorated by, after upgrading, vacuuming all
tables in all databases while having vacuum_freeze_table_age set to
zero. This will fix any latent corruption but will not be able to
fix all pre-existing data errors. However, an installation can be
presumed safe after performing this vacuuming if it has executed
fewer than 2^31 update transactions in its lifetime (check this
with SELECT txid_current() < 2^31).
+ Fix multiple bugs in MultiXactId freezing (Andres Freund, Alvaro
Herrera)
These bugs could lead to "could not access status of transaction"
errors, or to duplicate or vanishing rows. Users upgrading from
releases prior to 9.3.0 are not affected.
The issue can be ameliorated by, after upgrading, vacuuming all
tables in all databases while having vacuum_freeze_table_age set to
zero. This will fix latent corruption but will not be able to fix
all pre-existing data errors.
As a separate issue, these bugs can also cause standby servers to
get out of sync with the primary, thus exhibiting data errors that
are not in the primary. Therefore, it's recommended that 9.3.0 and
9.3.1 standby servers be re-cloned from the primary (e.g., with a
new base backup) after upgrading.
+ Fix initialization of "pg_clog" and "pg_subtrans" during hot
standby startup (Andres Freund, Heikki Linnakangas)
This bug can cause data loss on standby servers at the moment they
start to accept hot-standby queries, by marking committed
transactions as uncommitted. The likelihood of such corruption is
small unless, at the time of standby startup, the primary server
has executed many updating transactions since its last checkpoint.
Symptoms include missing rows, rows that should have been deleted
being still visible, and obsolete versions of updated rows being
still visible alongside their newer versions.
This bug was introduced in versions 9.3.0, 9.2.5, 9.1.10, and
9.0.14. Standby servers that have only been running earlier
releases are not at risk. It's recommended that standby servers
that have ever run any of the buggy releases be re-cloned from the
primary (e.g., with a new base backup) after upgrading.
* Refresh debian/patches/62-pg_upgrade-test-in-tmp.
