An updated perl-DBI package that fixes a temporary file flaw in DBI::ProxyServer is now available for CentOS Linux 4. This update has been rated as having low security impact by the CentOS Security Response Team.
DBI is a database access Application Programming Interface (API) for the Perl programming language. The Debian Security Audit Project discovered that the DBI library creates a temporary PID file in an insecure manner. A local user could overwrite or create files as a different user who happens to run an application which uses DBI::ProxyServer. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-0077 to this issue. Users should update to this erratum package which disables the temporary PID file unless configured.
