Description:
Secunia Research has discovered a vulnerability in Link Grammar, which can be exploited by malicious people to compromise an application using the affected code.
The vulnerability is caused due to a boundary error within the "separate_word()" function in tokenize.c when processing overly long words (over 61 bytes). This can be exploited to cause a stack-based buffer overflow via a specially crafted sentence passed to the "separate_sentence()" function.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 4.1b. Other versions may also be affected.
