StringBuilder in Microsoft Silverlight 5 before 5.1.50709.0 does not properly allocate memory for string-insert and string-append operations, which allows remote attackers to execute arbitrary code via a crafted web site, aka "Microsoft Silverlight Memory Corruption Vulnerability."
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.
