CVE 2008-2149
Stack-based buffer overflow in the searchwn function in Wordnet 2.0, 2.1, and 3.0 might allow context-dependent attackers to execute arbitrary code via a long command line option. NOTE: this issue probably does not cross privilege boundaries except in cases in which Wordnet is used as a back end.
