Summary

Software Description

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.

Ubuntu 10.10
