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) rep_srv.exe, possibly related to an integer overflow.
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.
