Secunia Security Advisory - Bennett R. Samowich has discovered a security issue in Crypt::ECB, which makes it easier for malicious people to brute force passwords. The security issue is caused due to an error, where plain texts containing the ASCII character 0 is incorrectly encoded. This results in a weaker encryption and encoding collisions and may e.g. make it easier to brute force passwords. The issue has been confirmed on version 1.1. Other versions may also be affected.
