Synopsis ========
The Ruby cgi.rb CGI library is vulnerable to a Denial of Service attack.
Background ==========
Ruby is a dynamic, open source programming language with a focus on simplicity and productivity.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/ruby < 1.8.5_p2 >= 1.8.5_p2
Description ===========
The read_multipart function of the CGI library shipped with Ruby (cgi.rb) does not properly check boundaries in MIME multipart content. This is a different issue than GLSA 200611-12.
Impact ======
The vulnerability can be exploited by sending the cgi.rb library a crafted HTTP request with multipart MIME encoding that contains a malformed MIME boundary specifier. Successful exploitation of the vulnerability causes the library to go into an infinite loop.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All Ruby users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.5_p2"
