Yukihiro Matsumoto Ruby 1.8.2

Multiple unspecified vulnerabilities in Ruby before 1.8.5 allow remote attackers to bypass "safe level" checks via unspecified vectors involving (1) the alias function and (2) "directory operations".

The read_multipart function in cgi.rb in Ruby before 1.8.5-p2 does not properly detect boundaries in MIME multipart content, which allows remote attackers to cause a denial of service (infinite loop) via crafted HTTP requests, a different issue than CVE-2006-5467.
