Red Hat: ruby security flaw
Summary
Summary
Ruby is an interpreted scripting language for object-oriented programming.Andres Salomon reported an insecure file permissions flaw in the CGIsession management of Ruby. FileStore created world readable files thatcould allow a malicious local user the ability to read CGI session data.The Common Vulnerabilities and Exposures project (cve.mitre.org) hasassigned the name CAN-2004-0755 to this issue.Users are advised to upgrade to this erratum package, which contains abackported patch to CGI::Session FileStore.
