    oxide-qt vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 16.04 LTS
    - 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 issue was discovered in Blink involving the provisional URL for an
    initially empty document. An attacker could potentially exploit this to
    spoof the currently displayed URL. (CVE-2016-5141)
    
    A use-after-free was discovered in the WebCrypto implementation 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
    application crash, or execute arbitrary code. (CVE-2016-5142)
    
    It was discovered that the devtools subsystem in Blink mishandles various
    parameters. An attacker could exploit this to bypass intended access
    restrictions. (CVE-2016-5143, CVE-2016-5144)
    
    It was discovered that Blink does not ensure that a taint property is
    preserved after a structure-clone operation on an ImageBitmap object
    derived from a cross-origin image. If a user were tricked in to opening a
    specially crafted website, an attacker could potentially exploit this to
    bypass same origin restrictions. (CVE-2016-5145)
    
    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-2016-5146, CVE-2016-5167)
    
    It was discovered that Blink mishandles deferred page loads. If a user
    were tricked in to opening a specially crafted website, an attacker could
    potentially exploit this to conduct cross-site scripting (XSS) attacks.
    (CVE-2016-5147)
    
    An issue was discovered in Blink related to widget updates. If a user were
    tricked in to opening a specially crafted website, an attacker could
    potentially exploit this to conduct cross-site scripting (XSS) attacks.
    (CVE-2016-5148)
    
    A use-after-free 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 application crash, or execute
    arbitrary code. (CVE-2016-5150)
    
    A use-after-free 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 application crash, or execute
    arbitrary code. (CVE-2016-5153)
    
    It was discovered that Chromium does not correctly validate access to the
    initial document. An attacker could potentially exploit this to spoof the
    currently displayed URL. (CVE-2016-5155)
    
    A use-after-free was discovered in the event 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 application
    crash, or execute arbitrary code. (CVE-2016-5156)
    
    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 application crash, or execute
    arbitrary code. (CVE-2016-5161)
    
    An issue was discovered with the devtools implementation. An attacker
    could potentially exploit this to conduct cross-site scripting (XSS)
    attacks. (CVE-2016-5164)
    
    An issue was discovered with the devtools implementation. An attacker
    could potentially exploit this to conduct cross-site scripting (XSS)
    attacks. (CVE-2016-5165)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 16.04 LTS:
      liboxideqtcore0                 1.17.7-0ubuntu0.16.04.1
    
    Ubuntu 14.04 LTS:
      liboxideqtcore0                 1.17.7-0ubuntu0.14.04.1
