Bug ID: 1610812 Summary: CVE-2017-2899 blender: Integer Overflow in imb_loadtiff 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 TIFF loading functionality of the Blender open-source 3d creation suite version 2.78c. A specially crafted '.tif' 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 use the file as an asset via the sequencer in order to trigger this vulnerability.
