    oxide-qt vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.04 LTS
    - Ubuntu 15.10
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Several security issues were fixed in Oxide.
    
    Software Description:
    - oxide-qt: Web browser engine for Qt (QML plugin)
    
    Details:
    
    An out of bounds write 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. (CVE-2016-1660)
    
    It was discovered that Blink assumes that a frame which passes same-origin
    checks is local in some cases. 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.
    (CVE-2016-1661)
    
    A use-after-free was discovered in the V8 bindings 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. (CVE-2016-1663)
    
    It was discovered that the JSGenericLowering class in V8 mishandles
    comparison operators. If a user were tricked in to opening a specially
    crafted website, an attacker could potentially exploit this to obtain
    sensitive information. (CVE-2016-1665)
    
    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.
    (CVE-2016-1666)
    
    It was discovered that the TreeScope::adoptIfNeeded function in Blink
    does not prevent script execution during node-adoption operations. If a
    user were tricked in to opening a specially crafted website, an attacker
    could potentially exploit this to bypass same origin restrictions.
    (CVE-2016-1667)
    
    It was discovered that the forEachForBinding in the V8 bindings in Blink
    uses an improper creation context. If a user were tricked in to opening a
    specially crafted website, an attacker could potentially exploit this to
    bypass same origin restrictions. (CVE-2016-1668)
    
    A buffer overflow was discovered in V8. 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. (CVE-2016-1669)
    
    A race condition was discovered in ResourceDispatcherHostImpl in Chromium.
    An attacker could potentially exploit this to make arbitrary HTTP
    requests. (CVE-2016-1670)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.04 LTS:
      liboxideqtcore0                 1.14.9-0ubuntu0.16.04.1
    
    Ubuntu 15.10:
      liboxideqtcore0                 1.14.9-0ubuntu0.15.10.1
    
    Ubuntu 14.04 LTS:
      liboxideqtcore0                 1.14.9-0ubuntu0.14.04.1
    
    In general, a standard system update will make all the necessary changes.
