Import patches-unapplied version 9.1.12-0ubuntu0.13.10 to ubuntu/saucy-security
Imported using git-ubuntu import.
Changelog parent: ec247477cc75140c4ae93bbf66b5baf9e0008704
New changelog entries:
* New upstream security/bugfix release. (LP: #1282677)
- Shore up GRANT ... WITH ADMIN OPTION restrictions.
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.
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.
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.
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.
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.
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.
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
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)
* The upstream tarballs no longer contain a plain HISTORY file, but point to
the html documentation. Add 70-history.patch to note the location of these
files in our changelog.gz file.

Import patches-unapplied version 9.1.11-0ubuntu0.13.10 to ubuntu/saucy-proposed
Imported using git-ubuntu import.
Changelog parent: 610a7790c1d18752ce5b3990187121fc46256237
New changelog entries:
* New upstream bug fix release. (LP: #1257211)
- Fix "VACUUM"'s tests to see whether it can update relfrozenxid.
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. 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 initialization of "pg_clog" and "pg_subtrans" during hot
standby startup.
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.

Changelog parent: 71503c22d6ddcca4f27404a5ad4f5def1f0ca2ea
New changelog entries:
* Urgency high because of critical remote data destruction vulnerability.
* New upstream security/bug fix release:
- Fix insecure parsing of server command-line switches.
A connection request containing a database name that begins with
"-" could be crafted to damage or destroy files within the server's
data directory, even if the request is eventually rejected.
[CVE-2013-1899] (Closes: #704479)
- Reset OpenSSL randomness state in each postmaster child process.
This avoids a scenario wherein random numbers generated by
"contrib/pgcrypto" functions might be relatively easy for another
database user to guess. The risk is only significant when the
postmaster is configured with ssl = on but most connections don't
use SSL encryption. [CVE-2013-1900]
- Make REPLICATION privilege checks test current user not
authenticated user.
An unprivileged database user could exploit this mistake to call
pg_start_backup() or pg_stop_backup(), thus possibly interfering
with creation of routine backups. [CVE-2013-1901]
- Fix GiST indexes to not use "fuzzy" geometric comparisons when it's
not appropriate to do so.
The core geometric types perform comparisons using "fuzzy"
equality, but gist_box_same must do exact comparisons, else GiST
indexes using it might become inconsistent. After installing this
update, users should "REINDEX" any GiST indexes on box, polygon,
circle, or point columns, since all of these use gist_box_same.
- Fix erroneous range-union and penalty logic in GiST indexes that
use "contrib/btree_gist" for variable-width data types, that is
text, bytea, bit, and numeric columns.
These errors could result in inconsistent indexes in which some
keys that are present would not be found by searches, and also in
useless index bloat. Users are advised to "REINDEX" such indexes
after installing this update.
- Fix bugs in GiST page splitting code for multi-column indexes.
These errors could result in inconsistent indexes in which some
keys that are present would not be found by searches, and also in
indexes that are unnecessarily inefficient to search. Users are
advised to "REINDEX" multi-column GiST indexes after installing
this update.
- See HISTORY/changelog.gz for details about the other bug fixes.
* Bump Standards-Version to 3.9.4 (no changes necessary).

New changelog entries:
[ Martin Pitt ]
* Add autopkgtest, moved from postgresql-common.

+ Prevent execution of enum_recv from SQL
The function was misdeclared, allowing a simple SQL command to crash the
server. In principle an attacker might be able to use it to examine the
contents of server memory. Our thanks to Sumit Soni (via Secunia SVCRP)
for reporting this issue. (CVE-2013-0255)
