Details

It was discovered that PostgreSQL did not properly enforce permissions
within sessions when PL/Perl and PL/Tcl functions or operators were
redefined. A remote authenticated attacker could exploit this to execute
arbitrary code with permissions of a different user, possibly leading to
privilege escalation.
