Description

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

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
