On the face of it, current versions of DBI are clean. But FYI...

Title: Perl: rmtree and DBI tmpfile vulnerabilities
Date: January 26, 2005

Synopsis ========
The Perl DBI library and File::Path::rmtree function are vulnerable to symlink attacks.
Background ==========
Perl is a cross platform programming language. The DBI is the standard database interface module for Perl.
Affected packages =================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-perl/dbi <= 1.38 *>= 1.37-r1
>= 1.38-r1
2 dev-lang/perl <= 5.8.6-r1 >= 5.8.6-r2
*>= 5.8.5-r3
*>= 5.8.4-r2
*>= 5.8.2-r2
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------Description ===========
Javier Fernandez-Sanguino Pena discovered that the DBI library creates temporary files in an insecure, predictable way (CAN-2005-0077). Paul Szabo found out that "File::Path::rmtree" also handles temporary files insecurely (CAN-2004-0452).
Impact ======
A local attacker could create symbolic links in the temporary files directory that point to a valid file somewhere on the filesystem. When the DBI library or File::Path::rmtree is executed, this could be used to overwrite files with the rights of the user calling these functions.
Workaround ==========
There are no known workarounds at this time.
Resolution ==========
All Perl users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-lang/perlAll DBI library users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-perl/dbiReferences ==========
