    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:
    
    It was discovered that Chromium did not properly handle the interaction
    of IPC, the gamepad API and V8. If a user were tricked in to opening a
    specially crafted website, an attacker could potentially exploit this to
    execute arbitrary code with the privileges of the user invoking the
    program. (CVE-2015-1233)
    
    A buffer overflow was discovered in the GPU service. 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. (CVE-2015-1234)
    
    It was discovered that Oxide did not correctly manage the lifetime of
    BrowserContext, resulting in a potential use-after-free in some
    circumstances. 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-2015-1317)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 14.10:
      liboxideqtcore0                 1.5.6-0ubuntu0.14.10.1
    
    Ubuntu 14.04 LTS:
      liboxideqtcore0                 1.5.6-0ubuntu0.14.04.2
    
    In general, a standard system update will make all the necessary changes.
