Description

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
