Description Dhananjay Arunesh 2019-05-10 08:35:57 UTC

An issue was discovered in AdvanceCOMP through 2.1. A NULL pointer dereference exists in the function be_uint32_read() located in endianrw.h. It can be triggered by sending a crafted file to a binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact when a victim opens a specially crafted file.

Comment 9 Marco Benatto 2019-05-16 19:36:58 UTC

A crafted MNG file can cause advmng application from advancecomp to crash due to segmentation fault leading to DoS.
An attacker can craft a MNG file to induce advmng to derreference a NULL pointer, this happens due to improper
validation of MNG chunks contained on the malicious file.

The crash happens at be_uint32_read() called from png_print_chunk() when advmng is trying to read the malformed chunck
data when it has an invlid chunck size.
