GLSA-200412-04 : Perl: Insecure temporary file creation

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


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-200412-04
(Perl: Insecure temporary file creation)

Some Perl modules create temporary files in world-writable
directories with predictable names.

Impact :

A local attacker could create symbolic links in the temporary
files directory, pointing to a valid file somewhere on the filesystem.
When a Perl script is executed, this would result in the file being
overwritten with the rights of the user running the utility, which
could be the root user.

Workaround :

There is no known workaround at this time.

Solution :

All Perl users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=perl-5.8.5-r2'

Risk factor :

Low / CVSS Base Score : 2.1
