Stalker-game » S.t.a.l.k.e.r.: Shadow Of Chernobyl : Security Vulnerabilities, CVEs, (Overflow)

Stack-based buffer overflow in the IPureServer::_Recieve function in S.T.A.L.K.E.R.: Shadow of Chernobyl 1.0006 and earlier allows remote attackers to execute arbitrary code via a compressed 0x39 packet, which is decompressed by the NET_Compressor::Decompress function.

Integer overflow in the NET_Compressor::Decompress function in S.T.A.L.K.E.R.: Shadow of Chernobyl 1.0006 and earlier allows remote attackers to cause a denial of service (server crash) via a crafted packet with a 0xc1 value that contains no compressed data, which triggers a copy of a large amount of memory.
