"The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2020:14359-1 advisory.

  - A race condition when running shutdown code for Web Worker led to a use-after-free vulnerability. This
    resulted in a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76,
    and Thunderbird < 68.8.0. (CVE-2020-12387)

  - The Firefox content processes did not sufficiently lockdown access control which could result in a sandbox
    escape. *Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects
    Firefox ESR < 68.8 and Firefox < 76. (CVE-2020-12388, CVE-2020-12389)

  - The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP POST data of a
    request, which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the
    command into a terminal, it could have resulted in the disclosure of local files. This vulnerability
    affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12392)

  - The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request,
    which can be controlled by the website. If a user used the 'Copy as cURL' feature and pasted the command
    into a terminal, it could have resulted in command injection and arbitrary command execution. *Note: this
    issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox ESR < 68.8,
    Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12393)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 75 and Firefox ESR
    68.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some
    of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.8,
    Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-12395)

  - A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to
    memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8,
    Firefox < 76, and Thunderbird < 68.8.0. (CVE-2020-6831)

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