logger.c in the logger plugin in WeeChat before 1.9.1 allows a crash via strftime date/time specifiers, because a buffer is not initialized.
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.
