Description Andrej Nemec 2016-11-23 08:50:06 UTC 
The vulnerability exists due to the library allocating space for the array using a value from the file, and then within the loop for initializing said array allowing a value within the file to modify the loop’s terminator. Due to this, an aggressor can cause the loop’s index to point outside the bounds of the array when initializing it. This is a heap-based buffer overflow, and can lead to code execution under the context of the application using the library.
