Incorrect control of environment variables in PostgreSQL
PL/Perl allows an
unprivileged database user to change sensitive process environment variables
(e.g. PATH). That often suffices to enable arbitrary code execution, even if
the attacker lacks a database server operating system user. Versions before
PostgreSQL 17.1, 16.5, 15.9, 14.14, 13.17, and 12.21 are affected.
The PostgreSQL project thanks Coby Abrams for reporting this problem.
