Description:
Luigi Auriemma has reported some vulnerabilities in S.T.A.L.K.E.R.: Shadow of Chernobyl, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
1) A boundary error within MultipacketReciever::RecievePacket() can be exploited to cause a stack-based buffer overflow via a specially crafted packet with 0x39 as the first byte.
Successful exploitation allows execution of arbitrary code.
2) An input validation error within NET_Compressor::Decompress() can be exploited to cause a buffer overflow via a specially crafted packet containing the byte 0xc1.
3) An error within MultipacketReciever::RecievePacket() can be exploited to cause the server to terminate via a specially crafted packet.
The vulnerabilities are reported in version 1.0006. Other versions may also be affected.
Solution:
Use in trusted network environments only.
