Heap-based buffer overflow in Adobe Reader 11.0.06 allows remote attackers to execute arbitrary code via unspecified vectors, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2014.
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.
