USN-1002-2: PostgreSQL vulnerability

Releases

• Ubuntu 10.10

Packages

• postgresql-8.4 -

Details

USN-1002-1 fixed vulnerabilities in PostgreSQL. This update provides the
corresponding update for Ubuntu 10.10.

Original advisory 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 10.10

• postgresql-pltcl-8.4 - 8.4.5-0ubuntu10.10
• postgresql-plperl-8.4 - 8.4.5-0ubuntu10.10

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
