More information:

Several vulnerabilities have been discovered in Rails, the Ruby web application framework. The Common Vulnerabilities and Exposures project identifies the following problems:

• CVE-2009-4214

  A cross-site scripting (XSS) vulnerability had been found in the strip_tags function. An attacker may inject non-printable characters that certain browsers will then evaluate. This vulnerability only affects the oldstable distribution (lenny).

• CVE-2011-2930

  A SQL injection vulnerability had been found in the quote_table_name method that could allow malicious users to inject arbitrary SQL into a query.

• CVE-2011-2931

  A cross-site scripting (XSS) vulnerability had been found in the strip_tags helper. An parsing error can be exploited by an attacker, who can confuse the parser and may inject HTML tags into the output document.

• CVE-2011-3186

  A newline (CRLF) injection vulnerability had been found in response.rb. This vulnerability allows an attacker to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via the Content-Type header.

For the oldstable distribution (lenny), this problem has been fixed in version 2.1.0-7+lenny2.

For the stable distribution (squeeze), this problem has been fixed in version 2.3.5-1.2+squeeze2.

For the unstable distribution (sid), this problem has been fixed in version 2.3.14.

We recommend that you upgrade your rails packages.
