Alpine: multiple firefox-esr packages: security update to 91.7.0-r0

critical Tenable Cloud Security Plugin ID 404462

Description

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

- An attacker could have caused a use-after-free by forcing a text reflow in an SVG object leading to a
potentially exploitable crash. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and
Thunderbird < 91.7. (CVE-2022-26381)

- When resizing a popup after requesting fullscreen access, the popup would not display the fullscreen
notification. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and Thunderbird < 91.7.
(CVE-2022-26383)

- If an attacker could control the contents of an iframe sandboxed with <code>allow-popups</code> but not
<code>allow-scripts</code>, they were able to craft a link that, when clicked, would lead to JavaScript
execution in violation of the sandbox. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and
Thunderbird < 91.7. (CVE-2022-26384)

- Previously Firefox for macOS and Linux would download temporary files to a user-specific directory in
<code>/tmp</code>, but this behavior was changed to download them to <code>/tmp</code> where they could be
affected by other local users. This behavior was reverted to the original, user-specific directory.
<br>*This bug only affects Firefox for macOS and Linux. Other operating systems are unaffected.*. This
vulnerability affects Firefox ESR < 91.7 and Thunderbird < 91.7. (CVE-2022-26386)

- When installing an add-on, Firefox verified the signature before prompting the user; but while the user
was confirming the prompt, the underlying add-on file could have been modified and Firefox would not have
noticed. This vulnerability affects Firefox < 98, Firefox ESR < 91.7, and Thunderbird < 91.7.
(CVE-2022-26387)
