FreeBSD 8.4 before p14, 9.1 before p17, 9.2 before p10, and 10.0 before p7 does not properly initialize the buffer between the header and data of a control message, which allows local users to obtain sensitive information from kernel memory via unspecified vectors.
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.
