    oxide-qt vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 14.10
    - Ubuntu 14.04 LTS
    
    Summary:
    
    Several security issues were fixed in Oxide.
    
    Software Description:
    - oxide-qt: Web browser engine library for Qt (QML plugin)
    
    Details:
    
    Several memory corruption bugs were discovered in ICU. 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-2014-7923, CVE-2014-7926)
    
    A use-after-free was discovered in the IndexedDB implementation. 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-2014-7924)
    
    A use-after free was discovered in the WebAudio 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
    renderer crash or execute arbitrary code with the privileges of the
    sandboxed render process. (CVE-2014-7925)
    
    Several memory corruption bugs were discovered in V8. 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-2014-7927, CVE-2014-7928, CVE-2014-7931)
    
    Several use-after free bugs were discovered in the DOM implementation 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-2014-7929, CVE-2014-7930, CVE-2014-7932,
    CVE-2014-7934)
    
    A use-after free 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-2014-7933)
    
    Multiple off-by-one errors were 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-2014-7937)
    
    A memory corruption bug was discovered in the fonts implementation. 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-2014-7938)
    
    It was discovered that ICU did not initialize memory for a data structure
    correctly. 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-2014-7940)
    
    It was discovered that the fonts implementation did not initialize memory
    for a data structure correctly. 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-2014-7942)
    
    An out-of-bounds read was discovered in Skia. 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. (CVE-2014-7943)
    
    An out-of-bounds read 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. (CVE-2014-7946)
    
    It was discovered that the AppCache proceeded with caching for SSL
    sessions even if there is a certificate error. A remote attacker could
    potentially exploit this by conducting a MITM attack to modify HTML
    application content. (CVE-2014-7948)
    
    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-2015-1205)
    
    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-2015-1346)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      liboxideqtcore0                 1.4.2-0ubuntu0.14.10.1
      oxideqt-codecs                  1.4.2-0ubuntu0.14.10.1
      oxideqt-codecs-extra            1.4.2-0ubuntu0.14.10.1
    
    Ubuntu 14.04 LTS:
      liboxideqtcore0                 1.4.2-0ubuntu0.14.04.1
      oxideqt-codecs                  1.4.2-0ubuntu0.14.04.1
      oxideqt-codecs-extra            1.4.2-0ubuntu0.14.04.1
    
    In general, a standard system update will make all the necessary changes.
