Stack-based buffer overflow in the inbound_cap_ls function in common/inbound.c in HexChat 2.10.2 allows remote IRC servers to cause a denial of service (crash) via a large number of options in a CAP LS message.
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.
