A security issue and two vulnerabilities have been reported in PostgreSQL, which can be exploited by malicious users to bypass certain security restrictions and compromise a vulnerable system.
1) An unspecified error in PL/Perl related to Safe.pm can be exploited to execute arbitrary Perl code on the database server.
Successful exploitation requires authentication and that PL/Perl is installed and enabled.
2) Insecure permissions on the "pltcl_modules" table can be exploited to execute arbitrary Tcl code on the database server.
Successful exploitation requires authentication and that PL/Tcl is installed and enabled.
3) A security issue is caused due to missing privilege checks for "ALTER USER" and "ALTER DATABASE" statements when being used in combination with "RESET ALL". This can be exploited to reset configuration parameters for a user's role or database that have been set by a superuser.
The vulnerabilities are reported in versions 8.4, 8.3, 8.2, 8.1, 8.0, and 7.4.
Solution: Update to version 8.4.4, 8.3.11, 8.2.17, 8.1.21, 8.0.25, or 7.4.29.
Provided and/or discovered by: Reported by the vendor.
