Ubuntu Security Notice 1822-1 - Multiple memory safety issues were discovered in Firefox. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. Cody Crews discovered that some constructors could be used to bypass restrictions enforced by their Chrome Object Wrapper (COW). An attacker could exploit this to conduct cross-site scripting (XSS) attacks. Various other issues were also addressed.
