New versions of dev-lang/perl have been released to address the remaining issues (CAN-2005-0448). The updated sections appear below. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-perl/DBI <= 1.38 *>= 1.37-r1 >= 1.38-r1 2 dev-lang/perl <= 5.8.6-r3 >= 5.8.6-r4 *>= 5.8.5-r5 *>= 5.8.4-r4 *>= 5.8.2-r4 ------------------------------------------------------------------- 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" is vulnerable to various race conditions (CAN-2004-0452, CAN-2005-0448). 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 or remove files with the rights of the user calling these functions. Resolution ========== All Perl users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose dev-lang/perl All DBI library users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose dev-perl/DBI References ========== [ 1 ] CAN-2004-0452 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0452 [ 2 ] CAN-2005-0077 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0077 [ 3 ] CAN-2005-0448 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0448 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-38.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
