Description


Marsu Pilami has discovered a vulnerability in NewsReactor, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when processing articles downloaded from a news server. This can be exploited to cause a stack-based buffer overflow via a specially crafted article with an overly long (greater than 200 bytes) yEncode "name" keyword posted to the news server.

Successful exploitation allows execution of arbitrary code.

The vulnerability is confirmed in build 20070220.21. Other versions may also be affected.


Solution:
Download articles from trusted news servers only.
