PlRPC: Arbitrary code execution — GLSA 201403-08

PlRPC uses Storable which allows for code execution prior to Authentication

Affected packages

Background

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

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

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