postgresql: add fix for CVE-2014-0062 Security Advisory
Race condition in the (1) CREATE INDEX and (2) unspecified ALTER TABLE commands in PostgreSQL before 8.4.20, 9.0.x before 9.0.16, 9.1.x before 9.1.12, 9.2.x before 9.2.7, and 9.3.x before 9.3.3 allows remote authenticated users to create an unauthorized index or read portions of unauthorized tables by creating or deleting a table with the same name during the timing window. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-0062 Signed-off-by: Yue Tao <Yue.Tao@windriver.com> Signed-off-by: Kai Kang <kai.kang@windriver.com> Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>

4Subject: [PATCH] Avoid repeated name lookups during table and index DDL.
5
6commit 820ab11fbfd508fc75a39c43ad2c1b3e79c4982b REL9_2_STABLE
7
8If the name lookups come to different conclusions due to concurrent
9activity, we might perform some parts of the DDL on a different table
10than other parts. At least in the case of CREATE INDEX, this can be
11used to cause the permissions checks to be performed against a
12different table than the index creation, allowing for a privilege
13escalation attack.
14
15This changes the calling convention for DefineIndex, CreateTrigger,
16transformIndexStmt, transformAlterTableStmt, CheckIndexCompatible
17(in 9.2 and newer), and AlterTable (in 9.1 and older). In addition,
18CheckRelationOwnership is removed in 9.2 and newer and the calling
19convention is changed in older branches. A field has also been added
20to the Constraint node (FkConstraint in 8.4). Third-party code calling
21these functions or using the Constraint node will require updating.
22
