A heap-based buffer overflow issue was discovered in ImageMagick's ImportMultiSpectralQuantum() function in MagickCore/quantum-import.c. An attacker could pass specially crafted file to convert, triggering an out-of-bounds read error, allowing an application to crash, resulting in a denial of service.
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
The product writes data past the end, or before the beginning, of the intended buffer.
