Severity: Normal Title: Perl: rmtree and DBI tmpfile vulnerabilities Date: January 26, 2005 Updated: March 15, 2005 Bugs: #75696, #78634, #79685 ID: 200501-38:03

Update ======
The rmtree race conditions were only partly fixed in the original GLSA. 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
