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