According to the versions of the firefox package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Multiple flaws were found in the processing of     malformed web content. A web page containing malicious     content could cause Firefox to crash or, potentially,     execute arbitrary code with the privileges of the user     running Firefox. (CVE-2017-5429, CVE-2017-5430,     CVE-2017-5432, CVE-2017-5433, CVE-2017-5434,     CVE-2017-5435, CVE-2017-5436, CVE-2017-5438,     CVE-2017-5439, CVE-2017-5440,     CVE-2017-5441, CVE-2017-5442, CVE-2017-5443,     CVE-2017-5444, CVE-2017-5445, CVE-2017-5446,     CVE-2017-5447, CVE-2017-5448, CVE-2017-5449,     CVE-2017-5451, CVE-2017-5454, CVE-2017-5455,     CVE-2017-5456, CVE-2017-5459, CVE-2017-5460,     CVE-2017-5464, CVE-2017-5465, CVE-2017-5466,     CVE-2017-5467,     CVE-2017-5469,CVE-2016-10195,CVE-2016-10196,CVE-2016-10     197)

Several vulnerabilities were discovered in libevent, an asynchronous event notification library. They would lead to Denial Of Service via application crash, or remote code execution.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3278-1 advisory.

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted message, an attacker could potentially exploit these to read uninitialized memory, cause a denial     of service via application crash, or execute arbitrary code. (CVE-2017-5429, CVE-2017-5430, CVE-2017-5436,     CVE-2017-5443, CVE-2017-5444, CVE-2017-5445, CVE-2017-5446, CVE-2017-5447, CVE-2017-5461, CVE-2017-5467)

    Multiple security issues were discovered in Thunderbird. If a user were tricked in to opening a specially     crafted website in a browsing context, an attacker could potentially exploit these to spoof the addressbar     contents, conduct cross-site scripting (XSS) attacks, cause a denial of service via application crash, or     execute arbitrary code. (CVE-2017-5432, CVE-2017-5433, CVE-2017-5434, CVE-2017-5435, CVE-2017-5437,     CVE-2017-5438, CVE-2017-5439, CVE-2017-5440, CVE-2017-5441, CVE-2017-5442, CVE-2017-5449, CVE-2017-5451,     CVE-2017-5454, CVE-2017-5459, CVE-2017-5460, CVE-2017-5464, CVE-2017-5465, CVE-2017-5466, CVE-2017-5469,     CVE-2016-10195, CVE-2016-10196, CVE-2016-10197)

    A flaw was discovered in the DRBG number generation in NSS. If an attacker were able to perform a machine-     in-the-middle attack, this flaw could potentially be exploited to view sensitive information.
    (CVE-2017-5462)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Several vulnerabilities were discovered in libevent, an asynchronous event notification library. They would lead to Denial Of Service via application crash, or remote code execution.

For Debian 7 'Wheezy', these problems have been fixed in version 2.0.19-stable-3+deb7u2.

We recommend that you upgrade your libevent packages.

An update of the libevent package has been released.

The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 52.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2017-13 advisory.

  - Fixed potential buffer overflows in generated Firefox code due to     [CVE-2016-6354](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-6354) issue in Flex.
    (CVE-2017-5469)

  - A use-after-free vulnerability in SMIL animation functions occurs when pointers to animation elements in     an array are dropped from the animation controller while still in use. This results in a potentially     exploitable crash. (CVE-2017-5433)

  - A use-after-free vulnerability occurs during transaction processing in the editor during design mode     interactions. This results in a potentially exploitable crash. (CVE-2017-5435)

  - An out-of-bounds write in the Graphite 2 library triggered with a maliciously crafted Graphite font. This     results in a potentially exploitable crash. This issue was fixed in the Graphite 2 library as well as     Mozilla products. (CVE-2017-5436)

  - An out-of-bounds write during Base64 decoding operation in the Network Security Services (NSS) library due     to insufficient memory being allocated to the buffer. This results in a potentially exploitable crash. The     NSS library has been updated to fix this issue to address this issue and Firefox ESR 52.1 has been updated     with NSS version 3.28.4. (CVE-2017-5461)

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