USN71-1 : postgresql vulnerability |

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 : Upgrade to : - libecpg-dev-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - libecpg4-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - libpgtcl-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - libpgtcl-dev-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - libpq3-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - postgresql-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - postgresql-client-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - postgresql-contrib-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - postgresql-dev-7.4.5-3ubuntu0.2 (Ubuntu 4.10) - postgresql-doc-7.4.5-3ubuntu0.2 (Ubuntu 4.10) Network Security Threat Level: High Networks Security ID: Vulnerability Assessment Copyright: Ubuntu Security Notice (C) 2005 Canonical, Inc. / NASL script (C) 2005 Michel Arboi |
