Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200501-38 (Perl: rmtree and DBI tmpfile vulnerabilities)

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.
Workaround :

There are no known workarounds at this time.

Solution

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
