The Local ZIM Server (zcs.exe) in Zilab Chat and Instant Messaging (ZIM) Server 2.1 and earlier allow remote attackers to execute arbitrary code via (1) heap-based buffer overflows involving multiple vectors including a long room name and a long source account, and (2) a stack-based buffer overflow with a long username in an information request. NOTE: some of these details are obtained from third party information.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
