A heap-based buffer overflow issue was discovered in ImageMagick's ReadTIM2ImageData() function in coders/tim2.c. A local attacker could trick the user in opening specially crafted file, 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.
