The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2021:1884-1 advisory.
The Mozilla Maintenance Service granted SERVICE_START access to BUILTIN|Users which, in a domain network, grants normal remote users access to start or stop the service. This could be used to prevent the browser update service from operating (if an attacker spammed the ‘Stop’ command); but also exposed attack surface in the maintenance service. Note: This issue only affected Windows operating systems older than Win 10 build 1709. Other operating systems are unaffected.. This vulnerability affects Thunderbird < 78.10.1, Firefox < 87, and Firefox ESR < 78.10.1. (CVE-2021-29951)
A locally-installed hostile program could send WM_COPYDATA
messages that Firefox would process incorrectly, leading to an out-of-bounds read. This bug only affects Firefox on Windows. Other operating systems are unaffected.. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR < 78.11. (CVE-2021-29964)
Mozilla developers reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR < 78.11. (CVE-2021-29967)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
