Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2020-28595)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Obj.cpp "load_obj()" functionality. A remote attacker can send a specially crafted obj file, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Heap-based buffer overflow (CVE-ID: CVE-2020-28598)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the "stl_fix_normal_directions()" functionality. A remote attacker can send a specially crafted AMF file, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Heap-based buffer overflow (CVE-ID: CVE-2020-28596)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the "Objparser::objparse()" functionality. A remote attacker can send a specially crafted obj file, trigger heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Use-after-free (CVE-ID: CVE-2020-28594)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in the "_3MF_Importer::_handle_end_model()" functionality. A remote attacker can use a specially crafted 3MF file and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
