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 = 1.37-r1 > = 1.38-r1 2 dev-lang/perl = 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 [ 2 ] CAN-2005-0077 [ 3 ] CAN-2005-0448 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200501-38 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.
