Several security issues were fixed in Oxide.
A race condition was discovered in the MutationObserver implementation in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2015-6789)
