Multiple stack-based buffer overflows in Intel Alert Management System (aka AMS or AMS2), as used in Symantec AntiVirus Corporate Edition (SAVCE) 10.x before 10.1 MR10, Symantec System Center (SSC) 10.x, and Symantec Quarantine Server 3.5 and 3.6, allow remote attackers to execute arbitrary code via (1) a long string to msgsys.exe, related to the AMSSendAlertAct function in AMSLIB.dll in the Intel Alert Handler service (aka Symantec Intel Handler service); a long (2) modem string or (3) PIN number to msgsys.exe, related to pagehndl.dll in the Intel Alert Handler service; or (4) a message to msgsys.exe, related to iao.exe in the Intel Alert Originator service. Múltiples desbordamientos de búfer basados en pila en Intel Alert Management System (también conocido como AMS o AMS2), como es usado en Symantec AntiVirus Corporate Edition (SAVCE) v10.x anterior a v10.1 MR10, Symantec System Center (SSC) v10.x,y Symantec Quarantine Server v3.5 y v3.6, permite a atacantes remotos ejecutar código de su elección a través de (1) una cadena larga para msgsys.exe, relacionada con la función AMSSendAlertAct en AMSLIB.dll en el servicio Intel Alert Handler (también conocido como servicio Symantec Intel Handler); una larga (2)cadena modem o (3) número PIN para msgsys.exe, relacionado con pagehndl.dll en el servicio Intel Alert Handler; o (4) un mensaje para msgsys.exe, relacionado con iao.exe en el servicio Intel Alert Originator . This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Symantec Alert Management System. Authentication is not required to exploit this vulnerability. The specific flaw exists within the AMSLIB.dll module while processing data sent from the msgsys.exe process which listens by default on TCP port 38292. The DLL allocates a fixed length stack buffer and subsequently copies a user-supplied string using memcpy without validating the size. • http://secunia.com/advisories/43099 http://secunia.com/advisories/43106 http://securitytracker.com/id?1024996 http://www.securityfocus.com/bid/45936 http://www.symantec.com/security_response/securityupdates/detail.jsp?fid=security_advisory&pvid=security_advisory&year=2011&suid=20110126_00 http://www.vupen.com/english/advisories/2011/0234 http://www.zerodayinitiative.com/advisories/ZDI-11-028 http://www.zerodayinitiative.com/advisories/ZDI-11-030 http://www.zerodayinitiative.com/advisories/ZDI-11-0 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

HDNLRSVC.EXE in the Intel Alert Handler service (aka Symantec Intel Handler service) in Intel Alert Management System (aka AMS or AMS2), as used in Symantec AntiVirus Corporate Edition (SAVCE) 10.x before 10.1 MR10, Symantec System Center (SSC) 10.x, and Symantec Quarantine Server 3.5 and 3.6, allows remote attackers to execute arbitrary programs by sending msgsys.exe a UNC share pathname, which is used directly in a CreateProcessA (aka CreateProcess) call. HDNLRSVC.EXE en el servicio Intel Alert Handler (también conocido como servicio Symantec Intel Handler) en Intel Alert Management System (también conocido como AMS o AMS2) como el utilizado en Symantec AntiVirus Corporate Edition (SAVCE) v10.x anterior a v10.1 MR10, Symantec System Center (SSC) v10.x, y Symantec Quarantine Server v3.5 y v3.6, permite a atacantes remotos ejecutar programas de su eleeción enviando msgsys.exe a una ruta de acceso compartido UNC que es usada directamente en la llamada CreateProcessA (también conocido como CreateProcess). This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of multiple Symantec products. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Intel Alert Originator (iao.exe) service. While processing messages sent from the msgsys.exe process a size check can be bypassed and a subsequent stack-based buffer overflow can be triggered. • http://secunia.com/advisories/43099 http://secunia.com/advisories/43106 http://securitytracker.com/id?1024997 http://www.securityfocus.com/bid/45935 http://www.symantec.com/security_response/securityupdates/detail.jsp?fid=security_advisory&pvid=security_advisory&year=2011&suid=20110126_01 http://www.vupen.com/english/advisories/2011/0234 http://www.zerodayinitiative.com/advisories/ZDI-11-029 https://exchange.xforce.ibmcloud.com/vulnerabilities/64942 https://exchange.xforce.ibmcloud.com/vulnerabilities/649 • CWE-20: Improper Input Validation •
