NewStart CGSL CORE 5.04 / MAIN 5.04 : firefox Multiple Vulnerabilities (NS-SA-2019-0053)
critical Nessus Plugin ID 127239

Synopsis
The remote machine is affected by multiple vulnerabilities.Description
The remote NewStart CGSL host, running version CORE 5.04 / MAIN 5.04, has firefox packages installed that are affected by multiple vulnerabilities:- 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.

Upgrade the vulnerable CGSL firefox packages. Note that updated packages may not be available yet. Please contact ZTE for more information.See Also
