Discussion

Ruby 'resolv.rb' Predictable Transaction ID and Source Port DNS Spoofing Vulnerability

Ruby is prone to a DNS-spoofing vulnerability because the software fails to securely implement random values when performing DNS queries.

Successfully exploiting this issue allows remote attackers to spoof DNS replies, allowing them to redirect network traffic and to launch man-in-the-middle attacks.

The following versions of Ruby are affected:

1.8.5 and prior
1.8.6-p286 and prior
1.8.7-p71 and prior
1.9 r18423 and prior
