Bug ID: 1610847 Summary: CVE-2017-12103 blender: Integer Overflow when it converts text rendered as a font into a curve 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 way that the Blender open-source 3d creation suite v2.78c converts text rendered as a font into a curve. A specially crafted .blend 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 open the file or use the file as a library in order to trigger this vulnerability.
