Gentoo Linux Security Advisory

Title: PlRPC: Arbitrary code execution (GLSA 201403-08)
Severity: normal
Exploitable: remote
Date: March 27, 2014
Bug(s): #497692
ID: 201403-08

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: dev-perl/PlRPC
Vulnerable: < 0.202.0-r2
Unaffected: >= 0.202.0-r2
Architectures: All supported architectures


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