        prior to version 60. Five of these vulnerabilities have been classified
        as critical. [1]


IMPACT

        The vendor has provided the following details regarding the 
        vulnerabilities:
        
        "#CVE-2018-12359: Buffer overflow using computed size of canvas 
        element
        
        Reporter
        
        Nils
        
        Impact
        
        critical
        
        Description
        
        A buffer overflow can occur when rendering canvas content while 
        adjusting the height and width of the <canvas> element dynamically,
        causing data to be written outside of the currently computed 
        boundaries. This results in a potentially exploitable crash.

        Bug 1459162
        
        #CVE-2018-12360: Use-after-free when using focus()
        
        Reporter
        
        Nils
        
        Impact
        
        critical
        
        Description
        
        A use-after-free vulnerability can occur when deleting an input 
        element during a mutation event handler triggered by focusing that 
        element. This results in a potentially exploitable crash.

        Bug 1459693
        
        #CVE-2018-12361: Integer overflow in SwizzleData
        
        Reporter

        Impact
        
        critical
        
        Description
        
        An integer overflow can occur in the SwizzleData code while 
        calculating buffer sizes. The overflowed value is used for 
        subsequent graphics computations when their inputs are not sanitized
        which results in a potentially exploitable crash.

        Bug 1463244
        
        #CVE-2018-12362: Integer overflow in SSSE3 scaler
        
        Reporter
        
        F. Alonso (revskills)
        
        Impact
        
        high
        
        Description
        
        An integer overflow can occur during graphics operations done by the
        Supplemental Streaming SIMD Extensions 3 (SSSE3) scaler, resulting 
        in a potentially exploitable crash.

        Bug 1452375
        
        #CVE-2018-5156: Media recorder segmentation fault when track type is
        changed during capture
        
        Reporter
        
        Nils
        
        Impact
        
        high
        
        Description
        
        A vulnerability can occur when capturing a media stream when the 
        media source type is changed as the capture is occuring. This can 
        result in stream data being cast to the wrong type causing a 
        potentially exploitable crash.

        Bug 1453127
        
        #CVE-2018-12363: Use-after-free when appending DOM nodes
        
        Reporter
        
        Nils
        
        Impact
        
        high
        
        Description
        
        A use-after-free vulnerability can occur when script uses mutation 
        events to move DOM nodes between documents, resulting in the old 
        document that held the node being freed but the node still having a
        pointer referencing it. This results in a potentially exploitable 
        crash.

        Bug 1464784
        
        #CVE-2018-12364: CSRF attacks through 307 redirects and NPAPI 
        plugins
        
        Reporter
        
        David Black
        
        Impact
        
        high
        
        Description
        
        NPAPI plugins, such as Adobe Flash, can send non-simple cross-origin
        requests, bypassing CORS by making a same-origin POST that does a 
        307 redirect to the target site. This allows for a malicious site to
        engage in cross-site request forgery (CSRF) attacks.

        Bug 1436241
        
        #CVE-2018-12365: Compromised IPC child process can list local 
        filenames
        
        Reporter
        
        Alex Gaynor
        
        Impact
        
        moderate
        
        Description
        
        A compromised IPC child process can escape the content sandbox and 
        list the names of arbitrary files on the file system without user 
        consent or interaction. This could result in exposure of private 
        local files.

        #CVE-2018-12371: Integer overflow in Skia library during edge 
        builder allocation
        
        Reporter
        
        anonymous
        
        Impact
        
        moderate
        
        Description
        
        An integer overflow vulnerability in the Skia library when 
        allocating memory for edge builders on some systems with at least 16
        GB of RAM. This results in the use of uninitialized memory, 
        resulting in a potentially exploitable crash.

        Bug 1465686
        
        #CVE-2018-12366: Invalid data handling during QCMS transformations

        Impact
        
        moderate
        
        Description
        
        An invalid grid size during QCMS (color profile) transformations can
        result in the out-of-bounds read interpreted as a float value. This
        could leak private data into the output.

        #CVE-2018-12367: Timing attack mitigation of 
        PerformanceNavigationTiming
        
        Reporter
        
        Andrea Marchesini
        
        Impact
        
        moderate
        
        Description
        
        In the previous mitigations for Spectre, the resolution or precision
        of various methods was reduced to counteract the ability to measure
        precise time intervals. In that work, PerformanceNavigationTiming 
        was not adjusted but it was found that it could be used as a 
        precision timer.

        #CVE-2018-12368: No warning when opening executable 
        SettingContent-ms files
        
        Reporter
        
        Abdulrahman Alqabandi
        
        Impact
        
        moderate
        
        Description
        
        Windows 10 does not warn users before opening executable files with
        the SettingContent-ms extension even when they have been downloaded
        from the internet and have the "Mark of the Web." Without the 
        warning, unsuspecting users unfamiliar with this new file type might
        run an unwanted executable. This also allows a WebExtension with the
        limited downloads.open permission to execute arbitrary code without
        user interaction on Windows 10 systems
        
        Note: this issue only affects Windows operating systems. Other 
        operating systems are unaffected.

        that some of these could be exploited to run arbitrary code.

MITIGATION

        The vendor recommends upgrading to the latest version of Mozilla 
        Thunderbird to address these issues. [1]
        
        The vendor also advises:
        
        "In general, these flaws cannot be exploited through email in the 
        Thunderbird product because scripting is disabled when reading mail,
        but are potentially risks in browser or browser-like contexts." [1]
