Details

It was discovered that the Safe.pm module as used by PostgreSQL did not
properly restrict PL/perl procedures. If PostgreSQL was configured to use
Perl stored procedures, a remote authenticated attacker could exploit this
to execute arbitrary Perl code. (CVE-2010-1169)

It was discovered that PostgreSQL did not properly check permissions to
restrict PL/Tcl procedures. If PostgreSQL was configured to use Tcl stored
procedures, a remote authenticated attacker could exploit this to execute
arbitrary Tcl code. (CVE-2010-1170)

It was discovered that PostgreSQL did not properly check privileges during
certain RESET ALL operations. A remote authenticated attacker could exploit
this to remove all special parameter settings for a user or database.
