Multiple stack-based buffer overflows in IAO.EXE in the Intel Alert Originator Service in Symantec Alert Management System 2 (AMS2), as used
Multiple stack-based buffer overflows in IAO.EXE in the Intel Alert Originator Service in Symantec Alert Management System 2 (AMS2), as used in Symantec System Center (SSS); Symantec AntiVirus Server; Symantec AntiVirus Central Quarantine Server; Symantec AntiVirus (SAV) Corporate Edition 9 before 9.0 MR7, 10.0 and 10.1 before 10.1 MR8, and 10.2 before 10.2 MR2; Symantec Client Security (SCS) 2 before 2.0 MR7 and 3 before 3.1 MR8; and Symantec Endpoint Protection (SEP) before 11.0 MR3, allow remote attackers to execute arbitrary code via (1) a crafted packet or (2) data that ostensibly arrives from the MsgSys.exe process.
