  - CVE-2015-7834: Multiple vulnerabilities in V8 fixed at     the tip of the 4.6 branch

USN-2770-1 fixed vulnerabilities in Oxide in Ubuntu 14.04 LTS and Ubuntu 15.04. This update provides the corresponding updates for Ubuntu 15.10.

It was discovered that ContainerNode::parserInsertBefore in Blink would incorrectly proceed with a DOM tree insertion 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-2015-6755)

A use-after-free was discovered in the service worker implementation 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-2015-6757)

It was discovered that Blink did not ensure that the origin of LocalStorage resources are considered unique. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2015-6759)

A race condition and memory corruption was discovered in FFmpeg. 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-2015-6761)

It was discovered that CSSFontFaceSrcValue::fetch in Blink did not use CORS 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-2015-6762)

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-2015-6763)

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-2015-7834).
