Mandrake Linux Security Advisory : postgresql (MDKSA-2005:040)
High Nessus Plugin ID 17139
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionA number of vulnerabilities were found and corrected in the PostgreSQL DBMS :
A flaw in the LOAD command could be abused by a local user to load arbitrary shared libraries and as a result execute arbitrary code with the privileges of the user running the postgresql server (CVE-2005-0227).
A permission checking flaw was found where a local user could bypass the EXECUTE permission check for functions using the CREATE AGGREGATE command (CVE-2005-0244).
Multiple buffer overflows were discovered in PL/PgSQL. A database user with permission to create plpgsql functions could trigger these flaws which could then lead to arbitrary code execution with the privileges of the user running the postgresql server (CVE-2005-0245 and CVE-2005-0247).
Finally, a flaw in the integer aggregator (intagg) contrib module was found. A user could create carefully crafted arrays and crash the server, causing a Denial of Service (CVE-2005-0246).
The updated packages have been patched to correct these problems.
SolutionUpdate the affected packages.
