Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code. Security researcher Abhishek Arya of Google Chrome Security Team discovered a series of use-after-free issues using the Address Sanitizer tool. Many of these issues are potentially exploitable, allowing for remote code execution. Various other issues have also been addressed.
