The remote Redhat Enterprise Linux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2011:0908 advisory.
ruby WEBrick log escape sequence (CVE-2009-4492)
Ruby WEBrick javascript injection flaw (CVE-2010-0541)
ruby: memory corruption in BigDecimal on 64bit platforms (CVE-2011-0188)
Ruby: Untrusted codes able to modify arbitrary strings (CVE-2011-1005)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
