"The remote SUSE Linux SLES11 host has packages installed that are affected by multiple vulnerabilities as referenced in
the SUSE-SU-2020:14584-1 advisory.

  - Uninitialized Use in V8 in Google Chrome prior to 87.0.4280.88 allowed a remote attacker to obtain
    potentially sensitive information from process memory via a crafted HTML page. (CVE-2020-16042)

  - Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow
    on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR <
    78.6. (CVE-2020-26971)

  - Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This
    could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6,
    and Firefox ESR < 78.6. (CVE-2020-26973)

  - When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly
    cast to the wrong type. This resulted in a heap user-after-free, memory corruption, and a potentially
    exploitable crash. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
    (CVE-2020-26974)

  - Using techniques that built on the slipstream research, a malicious webpage could have exposed both an
    internal network's hosts as well as services running on the user's local machine. This vulnerability
    affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-26978)

  - When an extension with the proxy permission registered to receive , the proxy.onRequest callback
    was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening
    View Source could have inadvertently leaked their IP address. This vulnerability affects Firefox < 84,
    Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-35111)

  - If a user downloaded a file lacking an extension on Windows, and then Open-ed it from the downloads
    panel, if there was an executable file in the downloads directory with the same name but with an
    executable extension (such as .bat or .exe) that executable would have been launched instead. *Note: This
    issue only affected Windows operating systems. Other operating systems are unaffected.*. This
    vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-35112)

  - Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5. 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 < 84, Thunderbird < 78.6, and
    Firefox ESR < 78.6. (CVE-2020-35113)

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