USN-1002-1: PostgreSQL vulnerability

Releases

• Ubuntu 10.04
• Ubuntu 9.10
• Ubuntu 9.04
• Ubuntu 8.04
• Ubuntu 6.06

Packages

• postgresql-8.1 -
• postgresql-8.3 -
• postgresql-8.4 -

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.10

• postgresql-pltcl-8.4 - 8.4.5-0ubuntu9.10
• postgresql-plperl-8.4 - 8.4.5-0ubuntu9.10

Ubuntu 9.04

• postgresql-plperl-8.3 - 8.3.12-0ubuntu9.04
• postgresql-pltcl-8.3 - 8.3.12-0ubuntu9.04

Ubuntu 8.04

• postgresql-plperl-8.3 - 8.3.12-0ubuntu8.04
• postgresql-pltcl-8.3 - 8.3.12-0ubuntu8.04

Ubuntu 6.06

• postgresql-plperl-8.1 - 8.1.22-0ubuntu0.6.06
• postgresql-pltcl-8.1 - 8.1.22-0ubuntu0.6.06

Ubuntu 10.04

• postgresql-pltcl-8.4 - 8.4.5-0ubuntu10.04
• postgresql-plperl-8.4 - 8.4.5-0ubuntu10.04

fixes. In general, a standard system update will make all the necessary
changes.
