Description

RedCloth Gem for Ruby contains a flaw that allows a cross-site scripting (XSS)
attack. This flaw exists because the program does not validate input when
parsing textile links before returning it to users. This may allow a remote
attacker to create a specially crafted request that would execute arbitrary
script code in a user's browser session within the trust relationship between
their browser and the server.
