Default fonts on OS X display some Tibetan characters as whitespace. When used in the addressbar as part of an IDN this can be used for domain name spoofing attacks. Note: This attack only affects OS X operating systems. Other operating systems are unaffected. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.

The version of Mozilla Thunderbird installed on the remote Windows host is prior to 52.2. It is, therefore, affected by multiple vulnerabilities :

  - Multiple memory corruption issues exist that allow an     unauthenticated, remote attacker to execute arbitrary     code by convincing a user to visit a specially crafted     website. (CVE-2017-5470)

  - A use-after-free error exists in the EndUpdate()     function in nsCSSFrameConstructor.cpp that is triggered     when reconstructing trees during regeneration of CSS     layouts. An unauthenticated, remote attacker can exploit     this, by convincing a user to visit a specially crafted     website, to cause a denial of service condition or the     execution of arbitrary code. (CVE-2017-5472)

  - A use-after-free error exists in the Reload() function     in nsDocShell.cpp that is triggered when using an     incorrect URL during the reload of a docshell. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-7749)

  - A use-after-free error exists in the Hide() function in     nsDocumentViewer.cpp that is triggered when handling     track elements. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-7750)

  - A use-after-free error exists in the nsDocumentViewer     class in nsDocumentViewer.cpp that is triggered when     handling content viewer listeners. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2017-7751)

  - A use-after-free error exists that is triggered when     handling events while specific user interaction occurs     with the input method editor (IME). An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2017-7752)

  - An out-of-bounds read error exists in the IsComplete()     function in WebGLTexture.cpp that is triggered when     handling textures. An unauthenticated, remote attacker     can exploit this to disclose memory contents.
    (CVE-2017-7754)

  - A use-after-free error exists in the SetRequestHead()     function in XMLHttpRequestMainThread.cpp that is     triggered when logging XML HTTP Requests (XHR). An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-7756)

  - A use-after-free error exists in ActorsParent.cpp due to     improper handling of objects in memory. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-7757)

  - An out-of-bounds read error exists in the     AppendAudioSegment() function in TrackEncoder.cpp that     is triggered when the number of channels in an audio     stream changes while the Opus encoder is in use. An     unauthenticated, remote attacker can exploit this to     disclose sensitive information. (CVE-2017-7758)

  - A flaw exists in the ReadCMAP() function in     gfxMacPlatformFontList.mm that is triggered when     handling tibetan characters in combination with macOS     fonts. An unauthenticated, remote attacker can exploit     this, via a specially crafted IDN domain, to spoof a     valid URL. (CVE-2017-7763)

  - A flaw exists in the isLabelSafe() function in     nsIDNService.cpp that is triggered when handling     characters from different unicode blocks. An     unauthenticated, remote attacker can exploit this, via a     specially crafted IDN domain, to spoof a valid URL and     conduct phishing attacks. (CVE-2017-7764)

  - An out-of-bounds read error exists in the Graphite     component in the readPass() function in Pass.cpp. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the disclosure of     memory contents. (CVE-2017-7771)

  - Multiple integer overflow conditions exist in the     Graphite component in the decompress() function in     Decompressor.cpp due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this to cause a denial of service condition     or the execution of arbitrary code. (CVE-2017-7772,     CVE-2017-7773, CVE-2017-7778)

  - An out-of-bounds read error exists in the Graphite     component in the readGraphite() function in Silf.cpp. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or disclose memory     contents. (CVE-2017-7774)

  - An out-of-bounds read error exists in the Graphite     component in getClassGlyph() function in Silf.cpp due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2017-7776)

  - A flaw exists in the Graphite component in the     read_glyph() function in GlyphCache.cpp related to use     of uninitialized memory. An unauthenticated, remote     attacker can exploit this to have an unspecified impact.

  - An out-of-bounds read error exists in the Graphite     component in getClassGlyph() function in Silf.cpp due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition. (CVE-2017-7776)

  - A flaw exists in the Graphite component in the     read_glyph() function in GlyphCache.cpp related to use     of uninitialized memory. An unauthenticated, remote     attacker can exploit this to have an unspecified impact.
    (CVE-2017-7777)
