PostgreSQL — свободная объектно-реляционная система управления базами данных.

The (1) brin_page_type and (2) brin_metapage_info functions in the pageinspect extension in PostgreSQL before 9.5.x before 9.5.2 allows attackers to bypass intended access restrictions and consequently obtain sensitive server memory information or cause a denial of service (server crash) via a crafted bytea value in a BRIN index page.

The libxslt support in contrib/xml2 in PostgreSQL 8.3 before 8.3.20, 8.4 before 8.4.13, 9.0 before 9.0.9, and 9.1 before 9.1.5 does not properly restrict access to files and URLs, which allows remote authenticated users to modify data, obtain sensitive information, or trigger outbound traffic to arbitrary external hosts by leveraging (1) stylesheet commands that are permitted by the libxslt security options or (2) an xslt_process feature, related to an XML External Entity (aka XXE) issue.

The xml_parse function in the libxml2 support in the core server component in PostgreSQL 8.3 before 8.3.20, 8.4 before 8.4.13, 9.0 before 9.0.9, and 9.1 before 9.1.5 allows remote authenticated users to determine the existence of arbitrary files or URLs, and possibly obtain file or URL content that triggers a parsing error, via an XML value that refers to (1) a DTD or (2) an entity, related to an XML External Entity (aka XXE) issue.

The PL/perl and PL/Tcl implementations in PostgreSQL 7.4 before 7.4.30, 8.0 before 8.0.26, 8.1 before 8.1.22, 8.2 before 8.2.18, 8.3 before 8.3.12, 8.4 before 8.4.5, and 9.0 before 9.0.1 do not properly protect script execution by a different SQL user identity within the same session, which allows remote authenticated users to gain privileges via crafted script code in a SECURITY DEFINER function, as demonstrated by (1) redefining standard functions or (2) redefining operators, a different vulnerability than CVE-2010-1168, CVE-2010-1169, CVE-2010-1170, and CVE-2010-1447.

The "make check" command for the test suites in PostgreSQL 9.3.3 and earlier does not properly invoke initdb to specify the authentication requirements for a database cluster to be used for the tests, which allows local users to gain privileges by leveraging access to this cluster.

The chkpass extension 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 does not properly check the return value of the crypt library function, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and crash) via unspecified vectors.

PostgreSQL, 9.2.x before 9.2.4, 9.1.x before 9.1.9, 9.0.x before 9.0.13, 8.4.x before 8.4.17, and 8.3.x before 8.3.23 generates insecure temporary files with predictable filenames, which has unspecified impact and attack vectors related to "graphical installers for Linux and Mac OS X."

Multiple stack-based buffer overflows in json parsing in PostgreSQL before 9.3.x before 9.3.10 and 9.4.x before 9.4.5 allow attackers to cause a denial of service (server crash) via unspecified vectors, which are not properly handled in (1) json or (2) jsonb values.

Multiple integer overflows in contrib/hstore/hstore_io.c in PostgreSQL 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 allow remote authenticated users to have unspecified impact via vectors related to the (1) hstore_recv, (2) hstore_from_arrays, and (3) hstore_from_array functions in contrib/hstore/hstore_io.c; and the (4) hstoreArrayToPairs function in contrib/hstore/hstore_op.c, which triggers a buffer overflow. NOTE: this issue was SPLIT from CVE-2014-0064 because it has a different set of affected versions.

Buffer overflow in the gettoken function in contrib/intarray/_int_bool.c in the intarray array module in PostgreSQL 9.0.x before 9.0.3, 8.4.x before 8.4.7, 8.3.x before 8.3.14, and 8.2.x before 8.2.20 allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via integers with a large number of digits to unspecified functions.
