SplitToVariants() in the ispell code, lseg_inside_poly() in geo_ops.c, and regex_selectivity_sub() in selectivity estimation could recurse until stack overflow; fix by adding check_stack_depth() calls. So could next() in the regex compiler, but that case is better fixed by converting its tail recursion to a loop. (We probably get better code that way too, since next() can now be inlined into its sole caller.) There remains a reachable stack overrun in the Turkish stemmer, but we'll need some advice from the Snowball people about how to fix that. Per report from Egor Chindyaskin and Alexander Lakhin. These mistakes are old, so back-patch to all supported branches. Richard Guo and Tom Lane Discussion: https://postgr.es/m/1661334672.728714027@f473.i.mail.ru |

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
