WordNet morph_init() buffer overflow
|wordnet-morphinit-bo (44849)||High Risk|
WordNet is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the morph_init() function. By sending an overly long request using the WNSEARCHDIR and WNHOMES environment variables, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

- CVE-2008-3908: Multiple buffer overflows in Princeton WordNet (wn) 3.0 allow context-dependent attackers to execute arbitrary code via (1) a long argument on the command line; a long (2) WNSEARCHDIR, (3) WNHOME, or (4) WNDBVERSION environment variable; or (5) a user-supplied dictionary (aka data file). NOTE: since WordNet itself does not run with special privileges, this issue only crosses privilege boundaries when WordNet is invoked as a third party component.
