high Nessus Plugin ID 153183

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5074-1 advisory.

 - Mozilla developers reported memory safety bugs present in Firefox 91. 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 Firefox < 92. (CVE-2021-38494)

 - Mixed-content checks were unable to analyze opaque origins which led to some mixed content being loaded.
 This vulnerability affects Firefox < 92. (CVE-2021-38491)

 - Mozilla developers reported memory safety bugs present in Firefox 91 and Firefox ESR 78.13. 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 Firefox ESR < 78.14, Thunderbird < 78.14, and Firefox < 92. (CVE-2021-38493)

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