Buffer overflow in util.c in libpurple in Pidgin before 2.10.8 allows remote HTTP servers to cause a denial of service (application crash) or possibly have unspecified other impact via an invalid chunk-size field in chunked transfer-coding 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.
