Description:
Haikz has reported a vulnerability in Cellosoft Tokens Object extension for Vitalize!, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the Tokens Object (nptoken.mox) extension when handling the "RemoveChr()" method. This can be exploited to cause a stack-based buffer overflow via an overly long (greater than 1024 bytes) string passed as argument to the affected method.
Successful exploitation allows execution of arbitrary code when a user visits a malicious website but requires that the Vitalize! browser plug-in is installed.
The vulnerability is reported in version 2.0.0.6. Other versions may also be affected.
Solution:
The Cellosoft Tokens Object will reportedly be removed from Vitalize.
Do not browse untrusted websites.
