Stack-based buffer overflow in the SpreadSheet Lotus 123 reader (wkssr.dll), as used in Autonomy KeyView 10.4 and 10.9, Symantec Mail Security, and possibly other products, allows remote attackers to execute arbitrary code via unspecified vectors related to floating point conversion in unknown record types.
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.
