Arbitrary Code Execution via Malformed 3MF File in PrusaSlicer

In libslic3r/GCode/PostProcessor.cpp in Prusa PrusaSlicer through 2.6.1, a crafted 3mf project file can execute arbitrary code on a host where the project is sliced and G-code exported.

Caphyon Ltd Advanced Installer 19.3 and earlier and many products that use the updater from Advanced Installer (Advanced Updater) are affected by a remote code execution vulnerability via the CustomDetection parameter in the update check function. To exploit this vulnerability, a user must start an affected installation to trigger the update check.

An out-of-bounds write vulnerability exists in the Admesh stl_fix_normal_directions() functionality of Prusa Research PrusaSlicer 2.2.0 and Master (commit 4b040b856). A specially crafted AMF file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.

A stack-based buffer overflow vulnerability exists in the Objparser::objparse() functionality of Prusa Research PrusaSlicer 2.2.0 and Master (commit 4b040b856). A specially crafted obj file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.

An out-of-bounds write vulnerability exists in the Obj.cpp load_obj() functionality of Prusa Research PrusaSlicer 2.2.0 and Master (commit 4b040b856). A specially crafted obj file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.

A use-after-free vulnerability exists in the _3MF_Importer::_handle_end_model() functionality of Prusa Research PrusaSlicer 2.2.0 and Master (commit 4b040b856). A specially crafted 3MF file can lead to code execution. An attacker can provide a malicious file to trigger this vulnerability.
