glibc: glibc: Heap Buffer Overflow in `scanf` with `%mc` format specifier and large width

A flaw was found in glibc GNU C Library. This vulnerability occurs when an application uses the scanf family of functions with a %mc format specifier, which is used for dynamically allocating memory for character input, and provides an explicit width greater than 1024. This specific combination c...
