CVE-2011-2705

Publication date 5 August 2011

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The SecureRandom.random_bytes function in lib/securerandom.rb in Ruby before 1.8.7-p352 and 1.9.x before 1.9.2-p290 relies on PID values for initialization, which makes it easier for context-dependent attackers to predict the result string by leveraging knowledge of random strings obtained in an earlier process with the same PID.
