Alpine: multiple firefox-esr packages: security update to 91.6.0-r0

critical Tenable Cloud Security Plugin ID 404460

Description

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

- Mozilla developers Paul Adenot and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox
96 and Firefox ESR 91.5. 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 < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. (CVE-2022-22764)

- If a user installed an extension of a particular type, the extension could have auto-updated itself and
while doing so, bypass the prompt which grants the new version the new requested permissions. This
vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. (CVE-2022-22754)

- If a user was convinced to drag and drop an image to their desktop or other folder, the resulting object
could have been changed into an executable script which would have run arbitrary code after the user
clicked on it. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6.
(CVE-2022-22756)

- If a document created a sandboxed iframe without <code>allow-scripts</code>, and subsequently appended an
element to the iframe's document that e.g. had a JavaScript event handler - the event handler would have
run despite the iframe's sandbox. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox
ESR < 91.6. (CVE-2022-22759)

- When importing resources using Web Workers, error messages would distinguish the difference between
<code>application/javascript</code> responses and non-script responses. This could have been abused to
learn information cross-origin. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox
ESR < 91.6. (CVE-2022-22760)
