Description Agostino Sarubbo gentoo-dev 2014-01-10 09:46:47 UTC
From ${URL} :

PlRPC is a Perl module that implements IDL-free RPCs. It is intended for cross-domain applications, but it 
fails to achieve that goal because it uses Storable, which is known to be insecure when deserializing 
(thawing) untrusted data. User name and password are transmitted using Storable, so code execution can 
happen before authentication.

The patches that exist just document the issues and are not real fixes.



>The actual proposed patch to upstream is here:


Based on the discussion in bug #1030572, there is no real "fix" for this as it seems that Storable 
deserialization is exposed prior to password-based authentication (see how AcceptUser is called in the 
server code).

MITRE assigned CVE-2013-7284 to this issue.

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
