Stack-based buffer overflows in the (1) xmlvarcharfromfile, (2) xmlclobfromfile, (3) xmlfilefromvarchar, and (4) xmlfilefromclob function calls in IBM DB2 8.1 allow remote attackers to execute arbitrary code via a 94-byte second argument, which causes the return address to be overwritten with a pointer to the argument.
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.
