The SelectionOwner::ProcessTarget function in ui/base/x/selection_owner.cc in the UI implementation in Google Chrome before 40.0.2214.91 uses an incorrect data type for a certain length value, which allows remote attackers to cause a denial of service (out-of-bounds read) via crafted X11 data.
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.
