NixOS vulnerability analysis and mitigation
Overview
A Null Pointer Dereference vulnerability exists in GPAC 1.1.0 via the xtra_box_write function in /box_code_base.c, which causes a Denial of Service. This vulnerability was fixed in commit 71f9871 (GITHUB).
Technical details
The vulnerability occurs in the xtra_box_write function when handling XtraBox data. When prop_size is less than 4, data2 remains NULL and gets assigned to tag->prop_value. This NULL value is later passed to gf_bs_write_data() function, causing a null pointer dereference when attempting to access the memory (GITHUB).
Impact
The vulnerability can lead to a Denial of Service condition when processing specially crafted input files, as the null pointer dereference causes the application to crash (GITHUB).
Exploitability
The vulnerability can be triggered by providing a specially crafted file to MP4Box with the -hint parameter. A proof of concept exists demonstrating the crash through null pointer dereference (GITHUB).
Mitigation and workarounds
The vulnerability has been fixed in commit 71f9871. Users should upgrade to a version containing this fix (GITHUB).
