The version of Firefox ESR installed on the remote Windows host is prior to 60.6.1. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2019-10 advisory.

  - Incorrect handling of \\proto\\ mutations may lead to type confusion in IonMonkey JIT code and can be     leveraged for arbitrary memory read and write. (CVE-2019-9813)

  - Incorrect alias information in IonMonkey JIT compiler for Array.prototype.slice method may lead to missing     bounds check and a buffer overflow. (CVE-2019-9810)

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

Security Fix(es) :

  - Mozilla: Memory safety bugs fixed in Firefox 66 and     Firefox ESR 60.6 (CVE-2019-9788)

  - Mozilla: Use-after-free when removing in-use DOM     elements (CVE-2019-9790)

Security issues fixed: &#9; 

  - update to Mozilla Thunderbird 60.6.1 (bsc#1130262) :

  - CVE-2019-9813: Fixed Ionmonkey type confusion with
    __proto__ mutations

  - CVE-2019-9810: Fixed IonMonkey MArraySlice incorrect     alias information Release notes:
    https://www.mozilla.org/en-US/security/advisories/mfsa20     19-12

The remote NewStart CGSL host, running version MAIN 4.05, has firefox packages installed that are affected by multiple vulnerabilities:

  - Incorrect convexity calculations in Skia in Google     Chrome prior to 72.0.3626.81 allowed a remote attacker     to perform an out of bounds memory write via a crafted     HTML page. (CVE-2019-5785)

  - The type inference system allows the compilation of     functions that can cause type confusions between     arbitrary objects when compiled through the IonMonkey     just-in-time (JIT) compiler and when the constructor     function is entered through on-stack replacement (OSR).
    This allows for possible arbitrary reading and writing     of objects during an exploitable crash. This     vulnerability affects Thunderbird < 60.6, Firefox ESR <     60.6, and Firefox < 66. (CVE-2019-9791)

  - Incorrect alias information in IonMonkey JIT compiler     for Array.prototype.slice method may lead to missing     bounds check and a buffer overflow. This vulnerability     affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and     Thunderbird < 60.6.1. (CVE-2019-9810)

  - Incorrect handling of __proto__ mutations may lead to     type confusion in IonMonkey JIT code and can be     leveraged for arbitrary memory read and write. This     vulnerability affects Firefox < 66.0.1, Firefox ESR <     60.6.1, and Thunderbird < 60.6.1. (CVE-2019-9813)

  - When proxy auto-detection is enabled, if a web server     serves a Proxy Auto-Configuration (PAC) file or if a PAC     file is loaded locally, this PAC file can specify that     requests to the localhost are to be sent through the     proxy to another server. This behavior is disallowed by     default when a proxy is manually configured, but when     enabled could allow for attacks on services and tools     that bind to the localhost for networked behavior if     they are accessed through browsing. This vulnerability     affects Firefox < 65. (CVE-2018-18506)

  - Mozilla developers and community members reported memory     safety bugs present in Firefox 65, Firefox ESR 60.5, and     Thunderbird 60.5. Some of these bugs showed evidence of     memory corruption and we presume that with enough effort     that some of these could be exploited to run arbitrary     code. This vulnerability affects Thunderbird < 60.6,     Firefox ESR < 60.6, and Firefox < 66. (CVE-2019-9788)

  - A use-after-free vulnerability can occur when a raw     pointer to a DOM element on a page is obtained using     JavaScript and the element is then removed while still     in use. This results in a potentially exploitable crash.
    This vulnerability affects Thunderbird < 60.6, Firefox     ESR < 60.6, and Firefox < 66. (CVE-2019-9790)

  - The IonMonkey just-in-time (JIT) compiler can leak an     internal JS_OPTIMIZED_OUT magic value to the running     script during a bailout. This magic value can then be     used by JavaScript to achieve memory corruption, which     results in a potentially exploitable crash. This     vulnerability affects Thunderbird < 60.6, Firefox ESR <     60.6, and Firefox < 66. (CVE-2019-9792)

  - A mechanism was discovered that removes some bounds     checking for string, array, or typed array accesses if     Spectre mitigations have been disabled. This     vulnerability could allow an attacker to create an     arbitrary value in compiled JavaScript, for which the     range analysis will infer a fully controlled, incorrect     range in circumstances where users have explicitly     disabled Spectre mitigations. *Note: Spectre mitigations     are currently enabled for all users by default     settings.*. This vulnerability affects Thunderbird <     60.6, Firefox ESR < 60.6, and Firefox < 66.
    (CVE-2019-9793)

  - A vulnerability where type-confusion in the IonMonkey     just-in-time (JIT) compiler could potentially be used by     malicious JavaScript to trigger a potentially     exploitable crash. This vulnerability affects     Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <     66. (CVE-2019-9795)

  - A use-after-free vulnerability can occur when the SMIL     animation controller incorrectly registers with the     refresh driver twice when only a single registration is     expected. When a registration is later freed with the     removal of the animation controller element, the refresh     driver incorrectly leaves a dangling pointer to the     driver's observer array. This vulnerability affects     Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox <     66. (CVE-2019-9796)

  - An integer overflow in path handling lead to a use after     free in Skia in Google Chrome prior to 71.0.3578.80     allowed a remote attacker to potentially exploit heap     corruption via a crafted HTML page. (CVE-2018-18356)

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