[GLSA-200611-12] Ruby: Denial of Service vulnerability Vulnerability Scan
Vulnerability Scan Summary
Ruby: Denial of Service vulnerability
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200611-12
(Ruby: Denial of Service vulnerability)
Zed Shaw, Jeremy Kemper, and Jamis Buck of the Mongrel project reported
that the CGI library shipped with Ruby is vulnerable to a remote Denial
of Service by an unauthenticated user.
The vulnerability can be exploited by sending the cgi.rb library an
HTTP request with multipart MIME encoding that contains a malformed
MIME boundary specifier beginning with "-" instead of "--". Successful
exploitation of the vulnerability causes the library to go into an
infinite loop waiting for additional non-existent input.
There is no known workaround at this time.
All Ruby users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.5-r3"
Threat Level: Medium
