Severity: high
Exploitable: remote
Date: July 11, 2005
Bug(s): #96784
ID: 200507-10

Synopsis

A vulnerability in XMLRPC.iPIMethods allows remote attackers to execute arbitrary commands.

Background

Ruby is an interpreted scripting language for quick and easy object-oriented programming. XML-RPC is a remote procedure call protocol encoded in XML.

Affected Packages

Package: dev-lang/ruby
Vulnerable: < 1.8.2-r2
Unaffected: >= 1.8.2-r2
Architectures: All supported architectures


Description

Nobuhiro IMAI reported that an invalid default value in "utils.rb" causes the security protections of the XML-RPC server to fail.

Impact

A remote attacker could exploit this vulnerability to execute arbitrary commands.

Workaround

There is no known workaround at this time.

Resolution

All Ruby users should upgrade to the latest available version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.2-r2"
