postgresql vulnerabilities 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 : The execution of custom PostgreSQL functions can be restricted with the EXECUTE privilege. However, previous versions did not check this privilege when executing a function which was part of an aggregate. As a result, any database user could circumvent the EXECUTE restriction of functions with a particular (but very common) parameter structure by creating an aggregate wrapper around the function. (CVE-2005-0244) Several buffer overflows have been discovered in the SQL parser. These could be exploited by any database user to crash the PostgreSQL server or execute arbitrary code with the rights of the server. (CVE-2005-0245, CVE-2005-0247) Finally, this update fixes a Denial of Service vulnerability of the contributed "intagg" module. By constructing specially crafted arrays, a database user was able to corrupt and crash the PostgreSQL server. (CVE-2005-0246). Please note that this module is part of the "postgresql-contrib" package, which is not officially supported by Ubuntu. Solution : Upgrade to : - libecpg-dev-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - libecpg4-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - libpgtcl-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - libpgtcl-dev-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - libpq3-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - postgresql-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - postgresql-client-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - postgresql-contrib-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - postgresql-dev-7.4.5-3ubuntu0.4 (Ubuntu 4.10) - postgresql-doc-7.4.5-3ubuntu0.4 (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 |
