 - A flaw exists related to speculative execution, which is used as a performance feature to speed up operations. This optimization can result in memory being cached during conditional branches handling out-of-bounds checks. Using a vulnerable code pattern, or a JIT engine or interpreter to generate such a pattern, an attacker can perform a Flush+Reload or Evict+Reload side-channel attack on the cache and disclose parts of the privileged kernel memory.
 - A flaw exists in the fundamental design related to out-of-order process execution, which is used as a performance feature to speed up operations. This optimization can result in memory being cached before exceptions are raised for restricted memory access. Using transient instructions in combination with a Flush+Reload side-channel attack a local attacker can disclose parts of the privileged kernel memory.
 - A flaw exists related to speculative execution, which is used as a performance feature to speed up operations. This optimization can result in memory being cached during indirect branch prediction. This may allow a local attacker to train the Branch Target Buffer (BTB) to trigger a false prediction to a specially crafted memory location, causing a speculative execution of a crafted gadget and the caching of arbitrary memory. Using a side-channel attack on the cache the attacker can disclose parts of the privileged kernel memory.

The version of Firefox installed on the remote macOS or Mac OS X host is prior to 57.0.2. It is, therefore, affected by a vulnerability as referenced in the mfsa2017-29 advisory.

  - A buffer overflow occurs when drawing and validating elements using Direct 3D 9 with the ANGLE graphics     library, used for WebGL content. This is due to an incorrect value being passed within the library during     checks and results in a potentially exploitable crash.  Note: This attack only affects Windows operating     systems. Other operating systems are unaffected. (CVE-2017-7845)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 52.5.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-28 advisory.

  - A buffer overflow occurs when drawing and validating elements using Direct 3D 9 with the ANGLE graphics     library, used for WebGL content.

Other operating systems are unaffected. (CVE-2017-7845)

  - When Private Browsing mode is used, it is possible for a web worker to write persistent data to IndexedDB     and fingerprint a user uniquely. IndexedDB should not be available in Private Browsing mode and this     stored data will persist across multiple private browsing mode sessions because it is not cleared when     exiting. (CVE-2017-7843)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
