=========================================================== Ubuntu Security Notice USN-70-1 January 25, 2005 libdbi-perl vulnerabilities CAN-2005-0077 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: libdbi-perl The problem can be corrected by upgrading the affected package to version 1.42-3ubuntu0.1. In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Javier Fernández-Sanguino Peña from the Debian Security Audit Project discovered that the module DBI::ProxyServer in Perl's DBI library created a PID file in an insecure manner. This could allow a symbolic link attack to create or overwrite arbitrary files with the privileges of the user invoking a program using this module (like 'dbiproxy'). Now the module does not create a such a PID file by default.
