Alpine: multiple firefox-esr packages: security update to 78.14.0-r0

high Tenable Self-Hosted Container Security Plugin ID 404443

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- When delegating navigations to the operating system, Firefox would accept the `mk` scheme which might
allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. *This bug
only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects
Firefox < 92, Thunderbird < 91.1, Thunderbird < 78.14, Firefox ESR < 78.14, and Firefox ESR < 91.1.
(CVE-2021-38492)

- 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)
