GLSA-200502-13 : Perl: Vulnerabilities in perl-suid wrapper

This script is Copyright (C) 2005-2016 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200502-13
(Perl: Vulnerabilities in perl-suid wrapper)

perl-suid scripts honor the PERLIO_DEBUG environment variable and
write to that file with elevated privileges (CAN-2005-0155).
Furthermore, calling a perl-suid script with a very long path while
PERLIO_DEBUG is set could trigger a buffer overflow (CAN-2005-0156).

Impact :

A local attacker could set the PERLIO_DEBUG environment variable
and call existing perl-suid scripts, resulting in file overwriting and
potentially the execution of arbitrary code with root privileges.

Workaround :

You are not vulnerable if you do not have the perlsuid USE flag
set or do not use perl-suid scripts.

Solution :

All Perl users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose dev-lang/perl

Risk factor :

Medium / CVSS Base Score : 4.6
