"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).
