WordNet morph.c and search.c buffer overflow

wordnet-morph-search-bo (44848) The risk level is classified as HighHigh Risk

Description:

WordNet is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the morph.c and search.c files. By sending a specially-crafted command line argument, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
