CWE
  • CWE-122 - Heap-based Buffer Overflow
Summary
Two heap-based buffer overflow vulnerabilities exists in the JPEG-JFIF lossless Huffman image parser functionality of Accusoft ImageGear 19.10. A specially-crafted file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger these vulnerabilities.This heap-based buffer overflow takes place when the `SOF3` precision is greater or equal than 9.
