Multiple heap-based buffer overflows in EMC RepliStor 6.2 before SP5 and 6.3 before SP2 allow remote attackers to execute arbitrary code via a crafted message to (1) ctrlservice.exe or (2) repsrv.exe, possibly related to an integer overflow.

EMC RepliStor Server Service before ESA-09-003 has a DoASOCommand Remote Code Execution Vulnerability. The flaw exists within the DoRcvRpcCall RPC function -exposed via the repsrv.exe process- where the vulnerability is caused by an error when the repsrv.exe handles a specially crafted packet sent by an unauthenticated attacker.

The RepliStor Server Service in EMC Replistor 6.1.3 allows remote attackers to execute arbitrary code via a size value that causes RepliStor to create a smaller buffer than expected, which triggers a buffer overflow when that buffer is used in a recv function call.

Multiple heap-based buffer overflows in EMC RepliStor 6.2 SP2, and possibly earlier versions, allow remote attackers to execute arbitrary code via crafted compressed data.

repserv.exe 6.3.1.3 in the server in EMC RepliStor allows remote attackers to cause a denial of service via a crafted packet to TCP port 7144.
