Synopsis
========
PlRPC uses Storable which allows for code execution prior to
Authentication

Background
==========
The Perl RPC Module is a Perl module that implements IDL-free RPCs.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-perl/PlRPC < 0.202.0-r2 >= 0.202.0-r2

Description
===========
PlRPC uses Storable module for serialization and deserialization of
untrusted data. Deserialized data can contain objects which can lead to
loading of foreign modules, and possible execution of arbitrary code.

Impact
======
A remote attacker could possibly execute
arbitrary code with the privileges of the process, or cause a Denial of
Service condition.

Workaround
==========
External authentication mechanism can be used with PlRPC such as TLS or
IPSEC.

Resolution
==========
All PlRPC users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-perl/PlRPC-0.202.0-r2"

References
==========
[ 1 ] CVE-2013-7284
