RHSA-2004:441 - Security Advisory

Topic

An updated ruby package that fixes insecure file permissions for CGI session
files is now available.

Description

Ruby is an interpreted scripting language for object-oriented programming.

Andres Salomon reported an insecure file permissions flaw in the CGI
session management of Ruby. FileStore created world readable files that
could allow a malicious local user the ability to read CGI session data.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0755 to this issue.

Users are advised to upgrade to this erratum package, which contains a
backported patch to CGI::Session FileStore.
