[***** Start Debian Security Advisory DSA-658-1 *****] Debian Security Advisory DSA-658-1 libdbi-perl -- insecure temporary file Date Reported: 25 Jan 2005 Affected Packages: libdbi-perl Vulnerable: Yes Security database references: In Mitre's CVE dictionary: CAN-2005-0077. More information: Javier Fernández-Sanguino Peña from the Debian Security Audit Project discovered that the DBI library, the Perl5 database interface, creates a temporary PID file in an insecure manner. This can be exploited by a malicious user to overwrite arbitrary files owned by the person executing the parts of the library. For the stable distribution (woody) this problem has been fixed in version 1.21 -2woody2. For the unstable distribution (sid) this problem has been fixed in version 1.46-6. We recommend that you upgrade your libdbi-perl package.
