Summary: oxide-qt vulnerabilities

Details: It was discovered that the ContainerNode::parserRemoveChild function in Blink mishandled widget updates in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1630) It was discovered that the PPB_Flash_MessageLoop_Impl::InternalRun function in Chromium mishandled nested message loops. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same-origin restrictions. (CVE-2016-1631) Multiple use-after-frees were discovered in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-1633, CVE-2016-1634, CVE-2016-1644) It was discovered that the PendingScript::notifyFinished function in Blink relied on memory-cache information about integrity-check occurrences instead of integrity-check successes. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass Subresource Integrity (SRI) protections. (CVE-2016-1636) It was discovered that the SkATan2_255 function in Skia mishandled arctangent calculations. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-1637) A use-after-free was discovered in Chromium. 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 application crash, or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1641) Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking the program. (CVE-2016-1642) A type-confusion bug was discovered 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-2016-1643) Multiple security issues were discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via renderer crash or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2016-2843) An invalid cast was discovered 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-2016-2844) It was discovered that the Content Security Policy (CSP) implementation in Blink did not ignore a URL's path component in the case of a ServiceWorker fetch. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-2845)
