| Descripción: | Description:
The remote host is missing an update to ruby
announced via advisory MDVSA-2011:097.
Multiple vulnerabilities have been identified and fixed in ruby:
Cross-site scripting (XSS) vulnerability in the WEBrick HTTP server
in Ruby allows remote attackers to inject arbitrary web script or HTML
via a crafted URI that triggers a UTF-7 error page (CVE-2010-0541).
The FileUtils.remove_entry_secure method in Ruby allows local users
to delete arbitrary files via a symlink attack (CVE-2011-1004).
The safe-level feature in Ruby allows context-dependent attackers
to modify strings via the Exception#to_s method, as demonstrated by
changing an intended pathname (CVE-2011-1005).
The VpMemAlloc function in bigdecimal.c in the BigDecimal class in
Ruby does not properly allocate memory, which allows context-dependent
attackers to execute arbitrary code or cause a denial of service
(application crash) via vectors involving creation of a large
BigDecimal value within a 64-bit process, related to an integer
truncation issue. (CVE-2011-0188).
