Description

Ruby contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered because the cgi::session's filestore stores session information in temporary files created without any regard to permissions. Permissions are set only using the umask value, which may disclose the CGI session variable data resulting in a loss of confidentiality

Classification

Location: Local Access Required
Attack Type: Information Disclosure
Impact: Loss of Confidentiality
Exploit: Exploit Public

Solution

Upgrade to version 1.6.7-3woody3 or 1.8.1+1.8.2pre1-4 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
