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

  - A use-after-free vulnerability can occur while     enumerating attributes during SVG animations with clip     paths. This results in a potentially exploitable crash.
    This vulnerability affects Thunderbird < 52.8,     Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR <     52.8. (CVE-2018-5154)

  - A use-after-free vulnerability can occur while adjusting     layout during SVG animations with text paths. This     results in a potentially exploitable crash. This     vulnerability affects Thunderbird < 52.8, Thunderbird     ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
    (CVE-2018-5155)

  - Same-origin protections for the PDF viewer can be     bypassed, allowing a malicious site to intercept     messages meant for the viewer. This could allow the site     to retrieve PDF files restricted to viewing by an     authenticated user on a third-party website. This     vulnerability affects Firefox ESR < 52.8 and Firefox <     60. (CVE-2018-5157)

  - The PDF viewer does not sufficiently sanitize PostScript     calculator functions, allowing malicious JavaScript to     be injected through a crafted PDF file. This JavaScript     can then be run with the permissions of the PDF viewer     by its worker. This vulnerability affects Firefox ESR <     52.8 and Firefox < 60. (CVE-2018-5158)

  - An integer overflow can occur in the Skia library due to     32-bit integer use in an array without integer overflow     checks, resulting in possible out-of-bounds writes. This     could lead to a potentially exploitable crash     triggerable by web content. This vulnerability affects     Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox <     60, and Firefox ESR < 52.8. (CVE-2018-5159)

  - A buffer overflow was found during UTF8 to Unicode     string conversion within JavaScript with extremely large     amounts of data. This vulnerability requires the use of     a malicious or vulnerable legacy extension in order to     occur. This vulnerability affects Thunderbird ESR <     52.8, Thunderbird < 52.8, and Firefox ESR < 52.8.
    (CVE-2018-5178)

  - Mozilla developers backported selected changes in the     Skia library. These changes correct memory corruption     issues including invalid buffer reads and writes during     graphic operations. This vulnerability affects     Thunderbird ESR < 52.8, Thunderbird < 52.8, and Firefox     ESR < 52.8. (CVE-2018-5183)

  - A use-after-free vulnerability can occur in the     compositor during certain graphics operations when a raw     pointer is used instead of a reference counted one. This     results in a potentially exploitable crash. This     vulnerability affects Firefox ESR < 52.7.3 and Firefox <     59.0.2. (CVE-2018-5148)

  - Memory safety bugs were reported in Firefox 59, Firefox     ESR 52.7, and Thunderbird 52.7. 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 < 52.8, Thunderbird ESR < 52.8, Firefox <     60, and Firefox ESR < 52.8. (CVE-2018-5150)

  - Sites can bypass security checks on permissions to     install lightweight themes by manipulating the baseURI     property of the theme element. This could allow a     malicious site to install a theme without user     interaction which could contain offensive or     embarrassing images. This vulnerability affects     Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox <     60, and Firefox ESR < 52.8. (CVE-2018-5168)
