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 6 Marco Benatto 2019-05-16 16:01:27 UTC

This issue affects the versions of advancecomp as shipped with Red Hat Enterprise Linux 7. Red Hat Product Security has rated this issue as having a security impact of Low. A future update may address this issue. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.

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.
