A heap-based buffer overflow vulnerability exists in the XWD parser functionality of Accusoft ImageGear 19.10. A specially-crafted file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
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 receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.
