Luigi Auriemma has discovered some vulnerabilities in Zilab Chat and Instant Messaging (ZIM) Server, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
1) Boundary errors within the "Local ZIM Server" (zcs.exe) can be exploited to cause stack-based or heap-based buffer overflows via overly long, specially crafted packets sent to default port 7700/TCP.
Successful exploitation allows execution of arbitrary code.
2) A NULL-pointer dereference error within the "Local ZIM Server" can be exploited to crash the service via a specially crafted packet sent to default port 7700/TCP.
The vulnerabilities are confirmed in version 2.0 and reported in version 2.1. Other versions may also be affected.
Solution: Use only in a trusted network environment.
