PlRPC uses Storable which allows for code execution prior to Authentication

2.  Impact Information


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


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.


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

3.  Resolution Information


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


All PlRPC users should upgrade to the latest version:

Code Listing 3.1: Resolution

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