Multiple buffer overflows in GNU MPFR 2.4.0 allow context-dependent attackers to cause a denial of service (crash) via the (1) mpfr_snprintf and (2) mpfr_vsnprintf functions.
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.
