A vulnerability has been found in Ruby which may allow for arbitrary command execution.
|Package||dev-lang/ruby on all architectures|
|Affected versions||< 2.2.9|
|Unaffected versions||>= 2.2.9|
Ruby is an interpreted object-oriented programming language. The elaborate standard library includes an HTTP server (“WEBRick”) and a class for XML parsing (“REXML”).
A command injection flaw was discovered in Net::FTP which impacts Ruby.
A remote attacker, by enticing a user to download and open a crafted file from a malicious FTP server, could execute arbitrary commands with the privileges of the process.
There is no known workaround at this time.
All Ruby users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/ruby-2.2.9:2.2"
