Bug ID: 1610861 Summary: CVE-2017-2905 blender: Integer Overflow in the CustomData Mesh loading functionality Product: Security Response Component: vulnerability Keywords: Security Severity: medium Priority: medium Assignee: security-response-team@redhat.com Reporter: lpardo@redhat.com CC: design-devel@lists.fedoraproject.org, hobbes1069@gmail.com, kwizart@gmail.com, luya_tfz@thefinalzone.net, negativo17@gmail.com, promac@gmail.com
An exploitable integer overflow exists in the 'CustomData' Mesh loading functionality of the Blender open-source 3d creation suite. A .blend file with a specially crafted external data file can cause an integer overflow resulting in a buffer overflow which can allow for code execution under the context of the application. An attacker can convince a user to edit an object within a .blend library in their Scene in order to trigger this vulnerability.
