array_set_element() and related functions allow an array to be enlarged by assigning to subscripts outside the current array bounds. While these places were careful to check that the new bounds are allowable, they neglected to consider the risk of integer overflow in computing the new bounds. In edge cases, we could compute new bounds that are invalid but get past the subsequent checks, allowing bad things to happen. Memory stomps that are potentially exploitable for arbitrary code execution are possible, and so is disclosure of server memory. To fix, perform the hazardous computations using overflow-detecting arithmetic routines, which fortunately exist in all still-supported branches. The test cases added for this generate (after patching) errors that mention the value of MaxArraySize, which is platform-dependent. Rather than introduce multiple expected-files, use psql's VERBOSITY parameter to suppress the printing of the message text. v11 psql lacks that parameter, so omit the tests in that branch. Our thanks to Pedro Gallegos for reporting this problem. Security: CVE-2023-5869 |

PostgreSQL tests ================ This directory contains a variety of test infrastructure as well as some of the tests in PostgreSQL. Not all tests are here -- in particular, there are more in individual contrib/ modules and in src/bin. Not all these tests get run by "make check". Check src/test/Makefile to see which tests get run automatically. authentication/ Tests for authentication (but see also below) examples/ Demonstration programs for libpq that double as regression tests via "make check" isolation/ Tests for concurrent behavior at the SQL level kerberos/ Tests for Kerberos/GSSAPI authentication and encryption ldap/ Tests for LDAP-based authentication locale/ Sanity checks for locale data, encodings, etc mb/ Tests for multibyte encoding (UTF-8) support modules/ Extensions used only or mainly for test purposes, generally not suitable for installing in production databases perl/ Infrastructure for Perl-based TAP tests recovery/ Test suite for recovery and replication regress/ PostgreSQL's main regression test suite, pg_regress ssl/ Tests to exercise and verify SSL certificate handling subscription/ Tests for logical replication
