The Mozilla Maintenance Service can be invoked by an unprivileged user to read 32 bytes of any arbitrary file on the local system by convincing the service that it is reading a status file provided by the Mozilla Windows Updater. The Mozilla Maintenance Service executes with privileged access, bypassing system protections against unprivileged users. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 52.2 and Firefox < 54.

  - 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 NS_main() function in updater.cpp     due to improper validation of input when handling     callback file path parameters. A local attacker can     exploit this to manipulate files in the installation     directory. (CVE-2017-7760)

  - A flaw exists in the Maintenance Service helper.exe     application that is triggered as permissions for a     temporary directory are set to writable by     non-privileged users. A local attacker can exploit this     to delete arbitrary files on the system. (CVE-2017-7761)

  - A flaw exists that is triggered when displaying URLs     including authentication sections in reader mode. An     unauthenticated, remote attacker can exploit this, via a     specially crafted URL, to spoof domains in the address     bar. (CVE-2017-7762)

  - 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)

  - A flaw exists that is triggered due to improper parsing     of long filenames when handling downloaded files. An     unauthenticated, remote attacker can exploit this to     cause a file to be downloaded without the     'mark-of-the-web' applied, resulting in security     warnings for executables not being displayed.
    (CVE-2017-7765)

  - A flaw exists in the Mozilla Maintenance Service that is     triggered when handling paths for the 'patch',     'install', and 'working' directories. A local attacker     can exploit this to execute arbitrary code with elevated     privileges. (CVE-2017-7766)

  - A flaw exists in the Mozilla Maintenance Service that is     triggered when being invoked using the Mozilla Windows     Updater. A local attacker can exploit this to overwrite     arbitrary files with random data. (CVE-2017-7767)

  - A flaw exists in the IsStatusApplying() function in     workmonitor.cpp that is triggered when logging the     update status. A local attacker can exploit this to read     32 bytes of arbitrary files. (CVE-2017-7768)

  - 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-2017-7778)

  - 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.
    (CVE-2017-7777)

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 NS_main() function in updater.cpp     due to improper validation of input when handling     callback file path parameters. A local attacker can     exploit this to manipulate files in the installation     directory. (CVE-2017-7760)

  - A flaw exists in the Maintenance Service helper.exe     application that is triggered as permissions for a     temporary directory are set to writable by     non-privileged users. A local attacker can exploit this     to delete arbitrary files on the system. (CVE-2017-7761)

  - 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)

  - A flaw exists that is triggered due to improper parsing     of long filenames when handling downloaded files. An     unauthenticated, remote attacker can exploit this to     cause a file to be downloaded without the     'mark-of-the-web' applied, resulting in security     warnings for executables not being displayed.
    (CVE-2017-7765)

  - A flaw exists in the Mozilla Maintenance Service that is     triggered when handling paths for the 'patch',     'install', and 'working' directories. A local attacker     can exploit this to execute arbitrary code with elevated     privileges. (CVE-2017-7766)

  - A flaw exists in the Mozilla Maintenance Service that is     triggered when being invoked using the Mozilla Windows     Updater. A local attacker can exploit this to overwrite     arbitrary files with random data. (CVE-2017-7767)

  - A flaw exists in the IsStatusApplying() function in     workmonitor.cpp that is triggered when logging the     update status. A local attacker can exploit this to read     32 bytes of arbitrary files. (CVE-2017-7768)

  - 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.
