Vulnerability Assessment Details

USN71-1 : postgresql vulnerability

Vulnerability Assessment Summary
postgresql vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- libecpg-dev
- libecpg4
- libpgtcl
- libpgtcl-dev
- libpq3
- postgresql
- postgresql-client
- postgresql-contrib
- postgresql-dev
- postgresql-doc


Description :

John Heasman discovered a local privilege escalation in the PostgreSQL
server. Any user could use the LOAD extension to load any shared
library into the PostgreSQL server
the library's initialisation
function was then executed with the permissions of the server.

Now the use of LOAD is restricted to the database superuser (usually
'postgres').

Note: Since there is no way for normal database users to create
arbitrary files, this vulnerability is not exploitable remotely, e. g.
by uploading a shared library in the form of a Binary Large Object
(BLOB) to a public web server.

Solution :
