The remote NewStart CGSL host, running version MAIN 4.05, has thunderbird packages installed that are affected by multiple vulnerabilities:
libical 1.0 allows remote attackers to cause a denial of service (use-after-free) via a crafted ics file.
(CVE-2016-5824)
A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements.
This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65. (CVE-2018-18500)
Mozilla developers and community members reported memory safety bugs present in Firefox 64 and Firefox ESR 60.4.
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 < 60.5, Firefox ESR < 60.5, and Firefox < 65. (CVE-2018-18501)
An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65. (CVE-2018-18505)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
