Description Jan Lieskovsky 2011-02-20 20:27:53 UTC

A security flaw was found in the Ruby method,
translating message of the exception into string
representation. An attacker could use this flaw
to modify arbitrary untainted strings into their
tainted equivalents by tricking the safe level
mechanism of this method.
